I'm not sure if this has been discussed elsewhere on AML. Some of the vintage collectors at Net54 discovered a forger who has been getting bogus signed 1909-1911 t206 cards passed by the major authenticators. If the forger was as good at covering his tracks as he is at replicating vintage autographs, he might have been able to get away with the scam indefinitely. Nobody knows how long this person has been at this. It's seriously freaking out vintage baseball autograph collectors.
Yet another reason I don't take third party authentication on face value.
I thought I'd share as a heads up.
I've been seeing blatant forgeries on all types of pre 1917 M, N, G, T, E, Cabinet and strip cards, as well as 1933 and 1934 Goudey cards for years upon years. IMO, the overwhelming majority are forged.
