I have hundreds of t206 for sale. I have a bunch of graded and ungraded in various conditions. most the ungraded are in the PR to VG range. Could work with you on putting together a great starter lot. I used to be a dealer who specialized in just T206 but I have been selling off all of my inventory to fund my new app
www.sportscardscanner.com. Send me a PM and let me know what sort of budget you are working with and we can start to put together a lot for you. I have plenty of references on this site and others, am the owner of t206cards.com, and my ebay store is t206cards-com.
