I'm asking because COMC is putting together a more exhaustive list of cards that they will not take for consignment without them having already been graded. Here's the current list:
1909 Cy Young (T206)
1909 Eddie Plank (T206)
1909 Honus Wagner (T206)
1909 Ty Cobb (T206)
1933 Babe Ruth (Goudey #53, #80, #144, and #181)
1933 Lou Gehrig (Goudey #92 and #160)
1951 Mickey Mantle (Bowman #253)
1952 Mickey Mantle (Topps #311)
1966-67 Bobby Orr rookie card (Topps #35)
1979-80 Wayne Gretzky rookie card (O-Pee-Chee and Topps #18)

Here were the ones I came up with off the top of my head:
1909 T206 Honus Wagner (wouldn't that be great?)
1909 T206 Fred Snodgrass "Nodgrass" error - some people just take an eraser to the S to try and hide it.
1909 T206 Joe Doyle "NY Nat'l" error
1909 T206 Sherry Magee "Magie" error
Note: The Eddie Plank isn't really an error card, just a tremendous Short Print, but it should stay on the list
Any Shoeless Joe Jackson pre-1930 card
1914 Baltimore News Babe Ruth
1947-66 W461 Exhibits with a white or gray back; to my knowledge, only creams are authentic. (Known subjects: Willie Mays, Hank Aaron, Ted Williams?)

I will probably go through etsy and some other sites to add to the list of commonly faked cards. I also recommended they put in some kind of floor, like every card over $5,000 value must be graded/authenticated to be listed for sale on COMC.
