7 Costly Mistakes Coin Collectors Make at Major Shows (And How to Avoid Them)

I’ve seen these mistakes over and over. Here’s how to avoid the pitfalls that trip up most people.

1. Not Pre-Planning with Dealers Before the Show

Why It’s a Problem

Many collectors walk into major coin shows like the Great American Coin Show with great enthusiasm—but little to no prior arrangements. This leads to missed opportunities, especially with top-tier dealers who are extremely busy and often have limited availability. I’ve seen countless collectors circle the room multiple times, only to find their favorite dealers buried in long lines or already sold out of key inventory.

Warning Signs You’re Making This Mistake

• You spend more time waiting than buying.
• You hear, “Sorry, just sold that one” more than once.
• You’re trying to negotiate on the spot for high-demand pieces.

How to Prevent It

Contact dealers at least 7–10 days in advance. Use email, direct messaging, or even a quick call. Ask:

• “Do you have any new Classic Head $5s, Early Gold, or specific die marriages coming in?”
• “Can I reserve first look at any incoming inventory?”
• “Are you accepting pre-show buy agreements?”

Many dealers—like CRO, Doug Winter, or Phil at EAC—offer pre-show buys or early access for trusted clients. This isn’t favoritism; it’s smart inventory management. By setting up pickups or holds ahead of time, you bypass the chaos and walk straight to the coins you want.

Recovery Strategy

If you missed the pre-show window, visit booths during off-peak hours—early Thursday afternoon or late Friday morning. These are often the least crowded times. Bring a list of target coins and be ready to act fast. A simple “I’ve been following your inventory online—can I see your latest Early Gold arrivals?” shows you’re serious and prepared.

2. Underestimating Dealer Availability and Booth Closures

The Hidden Risk of No-Shows

One of the most frustrating situations at any major show? Showing up to a booth—only to find it empty. This happened at the Great American Coin Show with both Legends and Peak Rarities (Dan), despite Dan being a show sponsor. No explanation, no notice. Just an empty table.

This isn’t uncommon. Dealers may leave early due to:

• Emergency personal issues
• Low foot traffic
• Inventory sold out faster than expected
• Logistical issues (shipping, staffing)

How to Prevent It

Never assume a dealer will be there all four days. Instead:

• Confirm their show schedule via email or social media the week before.
• Check the show’s official app or website for real-time booth updates.
• Plan to visit high-priority dealers on Day 1 or early Day 2.

Recovery Strategy

If a booth is closed, ask nearby dealers or show staff: “Do you know if [Dealer Name] plans to return tomorrow?” Sometimes they return later in the show. If not, request their contact info and follow up post-show. Many dealers offer mail-order options for missed coins.

3. Wasting Time on Inefficient Show Routes

The ‘Circle-and-Search’ Trap

It’s tempting to wander, especially at a spacious show like Rosemont. But aimless walking wastes time. I’ve seen collectors make five to six full passes around the room, only to realize they spent hours looking at empty tables or irrelevant inventory.

Warning Signs

• You’re using the show floor like a coin mall, not a targeted buying mission.
• You’re not keeping a real-time list of which dealers you’ve visited.
• You’re checking every slab, not just the grades and types you collect.

How to Prevent It

Create a show battle plan before you arrive:

1. List 5–7 priority dealers (with booth numbers).
2. Map a logical route to hit them in order.
3. Bring a small notebook or use a notes app to log: “Visited CRO – picked up 1808/7,” “Doug Winter – line too long, will return 3 PM,” etc.

Use the show’s floor map (often available as a PDF) to plan your path. Skip entire sections if they don’t align with your collecting niche. For example, if you’re focused on Early Gold, don’t waste time in the bullion section.

Recovery Strategy

If you’re lost or overwhelmed, take a 10-minute break in one of the open seating areas. Review your list, then re-route. It’s better to move with purpose than to burn out early.

4. Not Bringing Essential Tools (And Relying on Memory)

The ‘I’ll Remember It’ Fallacy

One of the most common—and avoidable—mistakes? Showing up without reference tools. I’ve seen collectors stand at a dealer’s table, pull out a slab, and say, “Hmm… I think this die state matches my other one.” Then they stare, unsure.

Why It Matters

Die marriages, attribution, and grade distinctions require precision. You can’t rely on memory or a magnifier alone. The guy who brought D. Haynor’s Classic Head book didn’t just look like a pro—he was one.

How to Prevent It

Every serious collector should bring:

• A printed reference guide (e.g., Haynor, Breen, Dannreuther)
• A digital tablet or phone with high-res photos of your collection
• A calibrated loupe (10x or higher)
• A checklist of die marriages, CAC requirements, or target grades

For example, if you’re hunting for a Rattler commemorative with a CAC sticker, bring a printout of known slabs with stickers. This lets you instantly compare and avoid overpaying for non-stickered or lower-grade pieces.

Recovery Strategy

If you forgot your tools, ask the dealer to use their reference materials. Most will accommodate serious buyers. Or, use a trusted third-party app like PCGS CoinFacts or NGC Census to cross-check die states and population reports on your phone.

5. Overlooking the ‘Back-to-School’ Show Timing

The Hidden Scheduling Trap

Late August shows—like the 2026 ANA in Pittsburgh—are increasingly scheduled right when schools reopen. This creates a major conflict for collectors who travel with families or are teachers/students themselves.

Why It’s a Problem

• Fewer attendees = slower sales = dealers may leave early.
• Travel costs rise as hotels fill with school groups.
• Vacation days are already used up post-summer.

How to Prevent It

Plan your show attendance like a CTO plans a product launch:

• Check the show dates 12–18 months in advance.
• Compare with local school calendars and holiday breaks.
• Book travel and lodging early—especially in cities like Pittsburgh, which have limited hotel capacity.

Pro tip: Missed the ideal dates? Consider attending the FUN Show in January. It’s right after the holidays, but it’s a proven coin market hotspot with strong dealer participation.

Recovery Strategy

If you can’t attend due to scheduling, leverage dealer relationships. Many will ship pre-show purchases or send photos of new inventory. Use WhatsApp or Telegram for real-time updates and alerts.

6. Poor Hygiene and Handling Practices (Yes, Really)

The ‘Yellow Towel’ Incident

I saw something that still makes me cringe: an older man wiping down UNC 2024/2025 quarters with a yellow towel before inspecting them through a loupe. This isn’t just unhygienic—it’s a form of coin damage risk, especially for raw coins.

Why It Matters

Even small fibers or oils from cloth can affect a coin’s surface, especially in high humidity. For rare or high-grade coins, improper handling can devalue them by hundreds or thousands.

How to Prevent It

• Never wipe coins—raw or slabbed.
• Use lint-free cloths or gloves only if handling raw coins.
• Inspect coins in good lighting (bring a portable LED if needed).
• Ask dealers to handle all slabbed coins—you observe, they hold.

Recovery Strategy

If a coin has been mishandled, don’t buy it. Politely decline: “I appreciate the offer, but I’m looking for untouched specimens.”

7. Failing to Network and Share Knowledge

The Lone Collector Myth

Some collectors treat shows like solo missions. But the best deals and insights come from conversations. I’ve seen collectors help dealers attribute Classic Head $5s, share registry set strategies, and even get exclusive access to upcoming auctions—all through casual talk.

How to Prevent It

• Introduce yourself to dealers by name.
• Ask: “What’s the most interesting coin you’ve seen this year?”
• Share your collecting goals openly—dealers will remember you.

Recovery Strategy

After the show, send a quick thank-you email: “Great seeing you at Rosemont—loved the 1838 QE you showed me.” This builds long-term trust and future opportunities.

Conclusion: Collect Smarter, Not Harder

The Great American Coin Show—and every major show—is a high-stakes, high-reward event. But the difference between a successful trip and a missed opportunity often comes down to preparation, timing, and respect.

To avoid the 7 critical mistakes:

• Pre-arrange buys with dealers.
• Visit high-priority booths early.
• Plan your route, don’t wander.
• Bring reference tools, not just cash.
• Check show dates against school calendars.
• Handle coins properly—no towels!
• Network like a pro—your next great coin is one conversation away.

Remember: The best collectors aren’t just buyers. They’re strategic, prepared, and respected. Do that, and you won’t just survive the show—you’ll dominate it.
