1971 O-Pee-Chee/OPC Baseball Cards![]() ![]() ![]() OPC did make several changes to their 1971 set including a complete redesign of the card backs. OPC also changed over 20 cards including the first "Traded" cards and added more EXPOS cards to the set including #202 and #289. 1971 OPC's short prints are legendary, at only 5% of Topps' production, making this set very rare even in Canada. Some say 1971 OPC short print high numbers are even scarcer than the very, very scarce 1952 Topps highs where most ended up being dumped deep into the Atlantic ocean.

Centering is the balance of the borders: top/bottom & left/right. On perfectly-centered cards, top/bottom borders match as do the left/right borders. Centering is presented as a set of numbers & directions and often included with the grade. Perfectly-centered is "50/50 t/b" AND "50/50 l/r". As centering gets worse, one number increases and the other decreases. For example: 90/10 t/b is considered extremely off-center top to bottom. The numbers add up to 100 (50/50, 60/40, 90/10 ...).
