The 1952 Topps Mantle Deception? Have You Been Fooled?

I have been a collector since 1957 & the 1951 Bowman Mickey card has ALWAYS been collected in hobby circles as his "rookie" card. But recently, the 1952 Topps Mickey Mantle has "magically" become the "new rookie" card of Mickey Can someone logically explain this to me? Last I can tell, 1951 comes before 1952, so how can a 1952 card be a rookie card, when a card issued a year earlier exists? Have you ever seen a 1952 Topps Willie mays rookie card? NO, but Mays also has a 1951 Bowman card.....so explain why Willies 1952 Topps card is not his rookie..... Mantle has a 1952 Bowman card, why isn't that ALSO his rookie card? yet I have never seen that card advertised as his rookie If your new to the hobby, Mickey Mantle's rookie card is his 1951 Bowman card, NOT his 1952 Topps card.... A seller cannot arbitrarily decide what a rookie card is or can one? Maybe I think Mickey's 1953 Topps card should be his rookie...would you fall for that? I hope not Bottom line, don't believe everything a seller tells you in his listing... many times they are just flat deceiving you.... other times they don't know & make stuff up to persuade you to buy their "rare" cardboard Please.... be a informed buyer....& don't listen to "hype"
