The Arbitrage Guide: Flipping I stopped using Pirate Ship because coins are excluded from coverage for Fast Profit

The Hidden Cost Eroding Your Flipping Margins

There’s money to be made in the numismatic market when you spot price gaps. But here’s what dealers won’t tell you about quick arbitrage — shipping insurance exclusions are quietly eating your profit on every flip.

I’ve been dealing coins professionally for over fifteen years. One lesson burned into me: the difference between a profitable flip and a breakeven gamble often comes down to something most collectors overlook — how you ship it. When I started flipping raw coins through PCGS and NGC slabs, I treated insurance as an afterthought. Then a $3,200 Mercury dime with stunning luster and original patina got denied by InsureShield through Pirate Ship. That’s when I realized my entire risk model was flawed.

This isn’t just about postage. It’s about the true cost of moving inventory, protecting your capital, and making sure that spread actually lands in your pocket.

Buy/Sell Spreads: Why Insurance Gaps Shrink Your Edge

The Spread Is Everything

In flipping, the spread is the gap between what you pay wholesale and what you realize at retail. A typical raw-to-slab flip might carry a 15-25% spread on a coin graded and returned. But when you factor in shipping costs, insurance premiums, and uninsured losses, that spread evaporates fast.

Here’s what most new flippers miss: paying $18 for a Pirate Ship label with “insurance” that excludes coins means you’re buying an illusion of protection. That $18 isn’t coverage — it’s a false sense of security.

• Typical raw-to-slab flip spread: 15-25%
• Average shipping + insurance cost per package: $8-$25
• Uninsured loss on a single $1,000 coin: 100% of value
• Break-even claims for $500/year collectibles policy: 2-3 claims at $100-$250 each

When InsureShield explicitly excludes coins, currency, bullion, and securities, every coin you ship through Pirate Ship is uninsured. The wording about “collectible coins with no currency value” is misleading — in practice, claims on numismatic coins get denied or disputed regularly.

Wholesale vs Retail: Accounting for Real-World Risk

True Wholesale Pricing Must Include Shipping Risk

As a dealer, I don’t just buy at one price and sell at another. I buy at a price that accounts for getting that coin to the buyer safely. When eBay defaults to ShipCover insurance — which also doesn’t cover coins — and you’re selling a raw MS-65 1921-S Morgan dollar for $450, you’re carrying full loss risk.

Here’s how I think about wholesale vs retail with shipping risk:

1. Acquisition Cost: What I pay at auction or from a fellow dealer
2. Grading Fee: PCGS or NGC submission costs plus return shipping
3. Shipping Risk Premium: I add 2-5% to acquisition cost for uninsured losses
4. Retail Price: Market-adjusted based on current sell-through rates
5. Actual Net: Retail minus all costs minus estimated loss allowance

If I’m flipping a raw coin I plan to submit for grading, the shipping risk doubles. That coin travels twice
