I only have about 15 t206 cards total so im not sure how good my advice will be but I do have some ideas. When it comes to places to find them, major auctions houses like REA or Sterling Sports auctions always seem to have a wide varitey. The BST board here has a whole section dedicated to the T206 set. I have also found that there are a few Facebook groups dedicated to tobacco era cards to be pretty helpful in finding a wide variety of t206 related stuff.

Granted i've only ever picked up the specific cards that i've wanted as i've gone along, but these places that I listed have been big helps in finding what ive needed.
