With American Eagles and other US minted coins you get the protection of law and the threat of the Secret Service investigating the counterfeiters. It's a whole different level of legal protections.
And with PCGS you get a guarantee of authenticity. Yeah, I know there have been some counterfeits of the coins and PCGS containers but authentic PCGS grading gets you some insurance.
No doubt some will get screwed out there however...
If you're just one of the regular people, the Secret Service couldn't care less. Someone I know bought a full set of circulated "Morgan dollars" that turned out to be counterfeit - every coin, including common dates. At first glance they looked ok, like a low to mid-grade set that someone put together over time, in an old blue Whitman folder. All the coins had the same gray circulated look to them, everything looked legit until you looked a little closer and weighed a few. The buyer in this case just wasn't experienced. The buyer knew the name, address (in Peabody), and phone number of the seller, who played dumb and promised to make good.
After weeks of chasing the seller, the buyer called the Secret Service and they couldn't have been less help if they tried. They made believe they were taking a report on the phone, including seller's info, and that was the end of that "investigation".
If you're buying a PCGS or NGC coin, for starters, look up the slab number on their web sites and confirm it's the same coin. Then look at the label printing and hologram with jewelers loupe and compare to a known good example. Also look at the seams on the edge of the case. If you buy much from unknown sources then a tester like the Sigma is worth having. It can even test through the slab or most other packaging.
