Went to a flea market this weekend and picked up a lot of around 200 cards from 1960-1974 including many high #s from the 60s-72 for 15 cents apiece (paid $35 total for that lot).
Also picked up this 56 Billy for $5. It was that price because it's OC and has a very faint hairline wrinkle (the crease doesn't go all the way through to the back). I'm not working on the 56 set, so I'll be moving it. Not sure about the others. Might use them as trade bait.
