If you had 100k to build a collection...

I'd probably focus on just one T206 back subset that has some difficulty in finding the cards. Something like Cycles, American Beauty's, Old Mill's, EPDG's, or Tolstoi's. There's no fun in just buying something easy over night and being done with the project. I'd maybe be satisfied for a week with my purchase. I'd rather have to search cards out over time to build a very special rare collection that maybe one or two people have done or come close to completing. But that's how my brain works. I've built custom cars and I enjoy the build more than the completion.
