I believe you’re misinterpreting Jim Hegan’s card. It doesn’t say “he has spent 9 years in majors”. It says, “In 9 Major League seasons,…”. It means in a 9 season span Jim caught 3 no-hitters, led A.L. in putouts by a catcher 3 of those seasons, and led in Assists two of those seasons. The 9 season span they are most likely talking about is 1946-1954. He didn’t do anything of note in his first two seasons (1941 & 1942). So saying, “in 9 seasons” sounds better than “in 11 seasons”.  But is not an incorrect statement.

Thanks for the feedback. I actually made a mistake saying he had played 10 years. He had played 11, as you state. At best, I think, that 9 year statement is a bit foggy . Glad you looked at my list. I have a ton more for you to peruse.

Hegan caught his no hitters  in 1947, 1948 and 1951 which means he caught them in a five year span and started only eight years before this card was printed.

It seems that Topps literally didn't even try when doing the back of Jim Thies' card XD

While I love looking through the cards, I'm frankly disappointed with all the mistakes I have found. They would round off pitchers ERA to the full inning and figure out the ERA from that, hence the difference in several  of the pitchers stats.Thank you for your interest and I hope you enjoy my lists  I will be compiling.
