probably reprocessed i have sets from 57- 07 , 2 of every ase, $5 and $10 gold 98-07 and a bunch of comm.
I've definately got over 90. more than I can count. I bought a huge collection from this cool guy off Craigslist for $180, but I calculated all of it later when I got home and the thing was worth $500+ actually.
I have all of the proof nickels dating back to 1951, all Kennedy proofs, and proof sets from 1955-on (except for the 1999 silver proof set, I just can't seem to rationalize spending $250 on one!).
I don't collect proof coins, but somehow over time a few ended up in the collection as either bargain purchases or part of larger groups of coins.
