There was a 50 card set of errors with different backs is there a list of this to add and trade?

First of all, I just have to say how insanely ridiculous the odds on the variations are. Secondly, I’m curious why so few of the RC’s actually get labeled as such? I don’t understand the inconsistency or I guess just the choice behind the selectivity.

I love the '72 Topps set/design and it's gimmicks ('In Action', 'Boyhood Photos', 'Traded', and even the Trophy cards). It's great that Topps brought back the 'In Action' cards for 2021 Heritage. However, it's not so great that Topps didn't put 'In Action' cards in Heritage High Number (for some reason, the puzzles on the back add to the fun).

I don’t have an opinion on others opinions, only mine. For that matter, I want to say that at first I didn’t care for this collection. But as I kept breaking packs and boxes I began to see why it’s a set for the times. It may be geared to attempt to attract all ages and likes, but what it does is allow a lower number of rookies and inserts to compliment the set. Although production may be higher than other sets, it’s affordability keeps it relevant and it’s lower number of rookies also give it a future for collectors.

I loved the card design in 1972 when I was 9! I loved them a few years ago when I built a set from scratch. And I love building this new set. Great design and colors! Way to go Topps!

Honestly not a fan of the 72 set. Hated it. But holding the 21 heritage in my grease stained fingers just does something. Maybe it is the scarity of cards over the last year, but i dont mind the set....
