Rarer variation, this is the 5¢ 4 card pack. As of 7/27/25, no 4 card packs graded higher on the PSA pop report
8/10 UPDATE - The cards in this pack are 100% 1964 Topps Cards, but these packs were sold in the Canadian market, hence the O-Pee-Chee information and french text on the back of the pack. There were no 1964 O-PEE-CHEE cards so this is a cool oddity with an OPC wrapper but Topps cards.
While researching the issue we found a group of 15 that sold in 2016 that seems to be the source for all of these that have come to market since. So certainly not something you see every day!
