Stepping in although I'm not the one you asked: I don't much like the slabbing/grading game, but there are LOTS AND LOTS of counterfeit gold coins floating around, especially in the smaller denominations where there's still a numismatic premium over melt. They've been heavily counterfeited since the 1960s at least. The raw "coin" you buy may be actual gold, but not an actual legit coin. Even if you buy slabbed, there are counterfeit slabs, too -- but so far, those are relatively easy to spot. The best bet is to buy from a trusted dealer (which means you'll pay a bit more than the bare minimum). Now, I haven't followed that advice myself, because I was raised to be a cheapskate, and I love bargain-hunting. So far, I've been lucky, as far as I know. Of all the gold I've bought, I've turned around and sold maybe half of it, mostly to experienced dealers, and so far it's all been good. In retrospect, though, I took some big chances, and -- yeah, lucky. If I'd just been accumulating all along, at this point I would be very nervous about some of the stuff I bought early on.
