Advice re seated liberty quarter
I am looking at a possible purchase and am wondering what some of the more experienced people here think. I've been offered the coin at sub $2k.
It's a pr66 1883 seated liberty quarter, NOT cameo or dcam. It is toned. I'm looking at pcgs price guide and it indicates 66 should run around $4k. Ebay of course is a dearth of lowballers. Gc has some interesting data indicating somewhere around mid $2k ish.
But I'm a bit confused about ms VS PL. When I tap ms is shows the $4k value (with recent auctions etc), but when I click PL it only shows a 67 for $15k value. Is the pr66 considered the same as ms, or would it fall under PL? Doesn't PL stand for proof like and pr stand for proof?
Thanks in advance. Any help and opinions appreciated.
