To the best of my knowledge, our hobby has never seen a true T-206 sheet, so it is very difficult to determine how many cards would have been on one. Many set experts have done a lot of research as to the placement of cards on a sheet, but I do not think there is a definitive answer.
The one example that comes to mind is the Honus Wagner proof strip of 5 that I believe Lelands sold a decade or two ago, with it going to Barry Halper and then to Steve Verkman, who then sold it in a private sale.
The only other sheet that I've ever heard of, is the one revolving around the T206 Wagner (PSA 8) story...and that's a can of worms I don't want to open.
