Inside I found some '71 OPC.
I bought them all.
First up, a stack of 44 cards, he called them "fillers". Total cost - $4. Did I mention it included 8 high numbers???
Next, some really nice looking cards. Two team cards. (my scanner ate one of the borders, but it's there)
Buford and Bench!
Rookie Stars!!! (Who?)
an unmarked checklist, no creases, just the famous chipping on the left side.
and a Home Run Leaders card, featuring the Natioal League.
Out of the 50 cards I bought, only two ended up being duplicates. So I'm happy there. And of the "fillers", I'm happy with the quality of 25 of them, so that doesn't leave too many to be upgraded when/IF I ever get this set done.
