Where to Get the Best Price for Vending Machine Coins: eBay or Coin Shows? A Dealer’s Guide to Selling Buffalo Nickels, Mercury Dimes, and Barber Quarters

The venue you choose to sell your item can drastically affect your net profit. Let’s compare the modern digital market to traditional dealer bourse floors.

As an online coin dealer who has spent years buying and selling everything from dateless Buffalo nickels to pristine Mercury dimes, I can tell you that the question of where to sell is just as important as what you’re selling. A recent forum discussion caught my eye — members were debating which coins historically passed through coin-operated machines. We’re talking gumball machines, vending machines, slot machines, jukeboxes, parking meters, and pay phones. That conversation got me thinking about something every collector and dealer needs to wrestle with: if you’ve pulled a bucket of Buffalo nickels from a vending machine hopper or found a cache of Barber quarters that once fed a 1940s Coke machine, where do you sell them to maximize your return?

In this guide, I’ll walk you through the real-world economics of selling on eBay versus selling at coin shows, drawing on my own experience grading, listing, and moving inventory through both channels. Whether you’re liquidating a collection of machine-circulated coins or trying to find the right home for a key-date piece that once rattled around in a slot machine tray, this article will help you make the smartest decision for your bottom line.

Why Vending Machine Coins Deserve a Second Look

Before we get into selling strategies, let’s take a moment to appreciate what we’re actually dealing with. That forum thread reminded me just how many denominations have cycled through coin-operated machines over the past century and a half. Here’s a quick historical overview of the major types:

• Penny machines (1850s–1970s): The earliest vending machines, dating back to the 1850s, accepted cents. Shield nickels and V nickels were heavily used in the first nickelodeons around the turn of the 20th century. Penny gumball machines persisted well into the 1970s, and some penny parking meters were still in use in certain Massachusetts towns into the 1990s.
• Nickel machines (1930s–present): Buffalo nickels were absolutely compatible with coin-operated machines — from 1930s slot machines and trade stimulators to Coke machines in the 1940s and 1950s. As one forum member noted, mechanical machines can’t tell the difference between a Jefferson nickel and a Buffalo nickel since they share the same diameter, weight, and metallic composition. Many collectors today still use dateless Buffalo nickels in restored vintage slot machines.
• Dime machines (1940s–1990s): Mercury dimes were widely accepted in vending machines, pay phones, and jukeboxes. By the late 1950s, a dime bought you a 16-ounce Pepsi. Pay phones accepted nickels, dimes, and quarters for toll calls, with local calls remaining a nickel for decades.
• Quarter machines (1950s–present): Barber quarters, Standing Liberty quarters, and Washington quarters all passed through machines extensively. By the 1980s and 1990s, seemingly every vending machine was calibrated for quarters. Laundromats, parking meters, and arcade machines all consumed vast quantities of quarters.
• Half dollar machines (1950s–1970s): Franklin halves were accepted in 1950s jukeboxes (some booths offered 7 songs for a half dollar). Laundromat change machines would give you five dimes for a half dollar. Half dollars circulated enough that machines were built to accept them.
• Dollar coin machines (1980s–present): Small dollars (Susan B. Anthony, Sacagawea, Presidential) were accepted in DC Metro vending machines, USPS stamp machines, and self-checkout lanes. Some 1980s pinball machines even tried SBA dollar coin acceptors, though the experiment was short-lived.

The key takeaway for sellers: coins that passed through machines are everywhere, and many of them carry fascinating provenance. A dateless Buffalo nickel that once fed a 1930s Bally slot machine has a story — and stories sell. But where you tell that story matters enormously.

The True Cost of Selling on eBay: Fees, Time, and Hidden Expenses

eBay is the 800-pound gorilla of online coin sales, and for good reason. The platform gives you access to millions of potential buyers worldwide. But as a dealer who lists regularly on eBay, I can tell you the costs add up fast — and they’re not always obvious.

eBay Fee Breakdown (What You Actually Keep)

As of 2024, eBay charges a final value fee of approximately 13.25% on most collectibles categories (coins and paper money fall under this). On top of that, there’s a $0.30 per-order fee. If you’re using eBay’s managed payments system (which is now standard), payment processing takes another 2.35% plus $0.25 per transaction.

Let’s do the math on a real example. Say you sell a lot of 10 Buffalo nickels — the kind you’d pull from a vending machine hopper — for $45.00 with free shipping:

• Final value fee (13.25%): $5.96
• Per-order fee: $0.30
• Payment processing (2.35% + $0.25): $1.31
• Shipping cost (padded envelope, tracking): $4.50
• Supplies (flipper, sleeve, label): $0.50
• Total costs: $12.57
• Net to you: $32.43 (72% of sale price)

That’s before you factor in your time — photographing the coins, writing the description, researching comps, answering buyer questions, packing, and driving to the post office. For lower-value items like circulated Buffalo nickels or Mercury dimes, eBay’s fee structure can eat a significant portion of your margin. I’ve run these numbers myself more times than I can count, and the takeaway is always the same: on cheap stuff, fees hurt.

When eBay Makes Sense

Despite the fees, eBay is the right choice in several scenarios:

1. You’re selling higher-value coins. On a $500 Mercury dime in MS-65 with booming luster and a sharp strike, the percentage-based fees are far more manageable relative to the profit margin.
2. You have rare or key-date pieces. The global buyer pool means you’re more likely to find the one collector who needs a 1921-D Mercury dime for their vending-machine-denomination set or a 1937-D 3-Legged Buffalo nickel to complete a date-and-mint collection.
3. You’re selling to a niche audience. Coins with specific provenance — like Buffalo nickels certified as having been used in slot machines, or Washington quarters from a documented vending machine hoard — can command real premiums from the right eBay audience. The eye appeal of a well-preserved patina combined with a great backstory is hard to beat.
4. You’ve built strong feedback and reputation. Sellers with 1,000+ positive feedback and detailed listings consistently get better prices. Buyers trust established sellers and are willing to pay more for that peace of mind.

The Coin Show Advantage: Dealer Buy Prices, Liquidity, and Face-to-Face Negotiation

Now let’s talk about the other side of the coin — literally. Coin shows (or “bourse floors,” as we call them) offer a completely different selling experience, and for many types of inventory, they’re far more efficient.

Understanding Dealer Buy Prices

When you walk up to a dealer’s table at a coin show with a box of machine-circulated coins, here’s what’s happening behind the counter. The dealer is thinking about:

• Immediate liquidity: Can I resell this today, this week, or will it sit in my case for months?
• Greysheet bid: What’s the Certified Coin Greysheet (or equivalent) bid for this coin in this grade?
• Overhead: I’m paying $200–$500 for this table, plus travel, hotel, and meals. I need to make this worth my time.
• Condition: These coins came out of vending machines — they’re going to be worn. A dateless Buffalo nickel is a dateless Buffalo nickel to most dealers, unless there’s a rare variety hiding in the mix.

In my experience, dealer buy prices at shows typically run 60–75% of retail for common-date, circulated coins. For key dates or better-condition pieces with strong eye appeal, you might get 75–85% of retail. The dealer needs margin to cover their costs and make a profit — that’s just the reality of the business.

Here’s a realistic example. You bring 50 circulated Buffalo nickels to a coin show — the kind with full rims but no readable dates, the sort that spent decades in vending machines and pay phones:

• Retail value (eBay, individually listed): $3.00–$5.00 each = $150–$250 total
• Dealer buy price (coin show): $1.50–$2.50 each = $75–$125 total
• Your net after eBay fees (if sold individually): ~$110–$180 (after fees, shipping, time)
• Your net from dealer (coin show): $75–$125 (instant, no fees, no shipping)

Notice something important? For common, low-value coins, the net difference between eBay and a coin show isn’t as dramatic as you’d think once you account for eBay’s fees and your time. And the coin show gives you cash in hand today. I can’t tell you how many times I’ve chosen the bird in hand over two in the bush — especially when I needed capital for the next deal.

Coin Show Etiquette: How to Get the Best Deal

I’ve been on both sides of the table, and I can tell you that how you approach a dealer at a show makes a huge difference in the price you receive. Here’s my advice:

1. Do your homework before you go. Know what your coins are worth. Check recent eBay sold listings (not asking prices — sold prices). Look up Greysheet values. Walk in informed, and dealers will take you seriously.
2. Organize your coins. Don’t dump a shoebox of unsorted coins on the dealer’s table. Have them sorted by denomination and approximate grade. Dealers respect sellers who respect their time — and they’ll reward that respect with better offers.
3. Lead with your best material. If you have a few better pieces — say, a 1938-D Buffalo nickel in Fine or a 1932-D Washington quarter — show those first. It sets the tone for the entire transaction and signals that you know quality.
4. Be willing to negotiate, but know your walk-away price. If a dealer offers you $80 for a lot you know is worth $150 on eBay, it’s okay to say, “I appreciate the offer, but I think I’ll try listing these online.” Sometimes they’ll improve the offer on the spot. Sometimes they won’t. Either way, you’ve lost nothing by asking.
5. Build relationships. The best deals at coin shows come from repeat interactions. If a dealer knows you consistently bring quality material with solid eye appeal, they’ll give you better prices because they trust your eye. I’ve had dealers call me when they’re looking for specific pieces — that kind of relationship is priceless.
6. Timing matters. Show up early in the morning when dealers are fresh and have cash. Avoid the last hour when they’re tired and packing up. The difference in offers between 9 AM and 4 PM at the same show can be surprising.

Liquidity: The Coin Show’s Secret Weapon

One thing eBay simply cannot compete with is speed. When you sell to a dealer at a coin show, you walk away with cash or a check in minutes. When you sell on eBay, you’re looking at:

• 1–7 days for the auction to end (if you run an auction)
• Time for the buyer to pay (some don’t pay immediately)
• 1–3 days for payment to clear
• Time to pack and ship
• Potential for returns, disputes, or chargebacks (which can take weeks to resolve)

For dealers and collectors who need to turn inventory quickly — maybe you’re freeing up capital for a better purchase, or you need cash for table fees at the next show — coin shows offer unmatched liquidity. I’ve had situations where I bought a collection on Saturday, sorted it that evening, and sold the common material to dealers at a show on Sunday morning, all within 24 hours. That kind of velocity is impossible on eBay, and it’s one of the reasons I keep coming back to the bourse floor.

Online Reputation: The Long Game on eBay

Here’s where eBay has a genuine long-term advantage: reputation building. Every successful sale on eBay adds to your feedback score, and over time, this creates a compounding benefit that’s hard to replicate anywhere else.

As an online dealer, I’ve watched my average sale price increase steadily as my feedback grew. Buyers are willing to pay more — sometimes 10–20% more — to buy from a seller with 5,000+ positive feedback versus a seller with 50. They trust the transaction. They trust the grading. They trust the shipping. That trust translates directly into higher bids and more Buy It Now sales.

This is especially important for coins with historical narratives. If you’re selling Buffalo nickels and you can tell the story — “These were pulled from a 1930s-era vending machine in Tonawanda, NY, the same town the Buffalo nickel gets its name from” — buyers on eBay will pay a small premium for that provenance. But only if they trust you. A new seller with no feedback will struggle to get those premiums, no matter how compelling the story.

My advice: if you plan to sell coins regularly, invest in building your eBay reputation. Start with lower-value items, deliver excellent service, photograph your coins well, grade honestly, and let the feedback accumulate. Within a year or two, you’ll be in a position to command significantly better prices. I wish someone had told me this when I started — it would have saved me a lot of underpriced listings.

The Hybrid Strategy: Using Both Channels for Maximum Profit

After years of selling coins through both channels, I’ve developed a hybrid approach that I recommend to every collector and dealer I work with. Here’s the framework:

Sell on eBay When:

• The coin retails for $50 or more
• It’s a key date, semi-key, or has unusual characteristics (VAMs, errors, interesting toning, exceptional luster)
• It has a compelling story or provenance (vending machine hoard, estate find, etc.) that adds to its collectibility
• You have the time and patience to photograph, list, and ship properly
• You’ve built sufficient seller reputation to command premium prices

Sell at Coin Shows When:

• The coin is common-date and circulated (dateless Buffalo nickels, common Mercury dimes, worn Barber quarters)
• You need cash quickly
• You have large quantities of similar material (bulk lots)
• The coins are low-value individually but have value as a group (a roll of AU 1950-D nickels pulled from a vending machine)
• You want to build dealer relationships for future buying opportunities

The Sweet Spot: eBay Auctions for Vending Machine Stories

One strategy I’ve found particularly effective is using eBay auctions to sell coins with documented vending machine provenance. For example, if you have a collection of coins that were literally pulled from a restored 1950s jukebox or a vintage slot machine, that story adds real numismatic value on eBay. Collectors love narrative. A lot titled “50 Buffalo Nickels from a 1930s Bally Slot Machine” will outsell a generic lot of 50 dateless Buffalo nickels every single time — I’ve seen it happen repeatedly.

The key is in the listing. Photograph the coins next to the machine if possible. Include the history. Mention the specific machine model and its era. Describe the patina and surfaces honestly. This is the kind of content that drives clicks, watchers, and ultimately, higher bids. I once sold a group of Mercury dimes pulled from a decommissioned pay phone for nearly triple what I would have gotten from a dealer — because the listing told a story that collectors connected with.

Practical Tips for Selling Machine-Circulated Coins

Regardless of which channel you choose, here are some practical tips specific to coins that have passed through vending machines, slot machines, and other coin-operated devices:

1. Grade honestly. Most machine-circulated coins will be in the AG to VF range. Don’t overgrade. Buyers — whether eBay collectors or coin show dealers — will notice, and it will hurt your reputation. A coin with honest wear and attractive original surfaces will always outsell an overgraded disappointment.
2. Look for better dates. Even in a bucket of dateless Buffalo nickels, you might find a 1938-D or a 1937-D 3-Legged variety. Always sort carefully before selling. I’ve found better dates mixed into bulk machine coins more times than I can count — that quick scan with a loupe has paid for itself a hundred times over.
3. Check for errors and varieties. Vending machine coins are often overlooked by collectors, which means errors and VAMs can lurk in these populations. A repunched mint mark or doubled die on a Mercury dime could be worth multiples of the common price. The collectibility of these pieces far exceeds their face value or even their melt.
4. Consider bulk pricing. For common, low-grade coins, selling in lots of 10, 25, or 50 is more efficient than listing individually. On eBay, this reduces your per-coin fee burden. At coin shows, dealers prefer buying larger quantities — it’s less work for them and better value for you.
5. Don’t clean them. I shouldn’t have to say this, but I will: never clean coins that came from vending machines. Original surfaces — even worn ones with a natural patina — are always preferable to cleaned ones. Cleaning destroys numismatic value. Full stop.

The Bottom Line: Know Your Coins, Know Your Channels

The forum discussion that inspired this article was really about something deeper than which coins fit in which machines. It was about the rich, tangible history embedded in everyday currency — the Buffalo nickel that bought a Coke for a nickel in the 1940s, the Mercury dime that played a song on a jukebox, the penny that rode a mechanical horse at a department store. These coins carry stories, and stories have value.

As a seller, your job is to match the right coin with the right channel to capture that value. For common, circulated machine coins, coin shows offer speed, simplicity, and reasonable returns. For rare dates, better-condition pieces with strong eye appeal, and coins with compelling provenance, eBay’s global audience and storytelling potential can deliver superior prices — especially if you’ve invested in building your online reputation.

The smartest dealers I know use both channels strategically. They sell the bulk material at shows to maintain cash flow and dealer relationships, and they list the premium pieces on eBay to maximize profit. It’s not either/or — it’s both, applied with intention and a clear understanding of what each channel does best.

So the next time you’re sorting through a collection of coins that once clinked and clanked their way through America’s vending machines, slot machines, and pay phones, take a moment to appreciate the history in your hands. Then make a smart, informed decision about where to sell. Your wallet will thank you.
