Good point. So I looked up their population report, which I'm not experienced with yet, but here it is: https://www.pcgs.com/coinfacts/coin/1972-s-1-silver/7411 But I don't see history, just current. And what the heck is this? AUCTION RECORD: $5,750 • MS67 • 09-21-2005 • Heritage Auctions Click on that link and you get the auction result. The PCGS price is $35 but someone paid $5750? What am I missing!? Oh, wait, it says "Double Struck in Collar, Close Overlap" So they are paying for an error coin.
