There are only two cards in the T206 set that were errors and corrected during production, Doyle N.Y. Nat'l and Magie.

Many other players names were misspelled and Ellam was given the wrong team designation, but none of them were corrected like the Doyle and Magie. The other things I believe you're referring to are print anomalies or quality control issues and not actual changes made to the card. The Doyle error was caught quickly resulting in a small number of these cards being distributed. Less than 10 are known and that makes it the scarcest of the 524 subjects in the set.
