I bought these 4 coins sometime in the past 2 years, but only found them in a box of unrelated stuff last week. (I moved last year, and some of the last-minute packing was done randomly.
Topps' 1964 coin set was made up of the "regular coins" and "All-Stars". Some players were featured on both types of coins. I've noticed that the All-Star coins tend to be in much better condition, while all the regular coins have heavily-tarnished edges and backs, as well as some on the front. Maybe different metals were used?
These 4 coins bring my 1964 collection to 9 coins, joining these which I got a few years ago. (I also have the Tony Taylor coin.)
I didn't collect Topps' baseball coins back in the day, because I didn't collect baseball cards in either 1964 or 1971.
