I started going to card conventions with my Dad when I was 5. I stopped for a while in high school. Got interested again when ebay started. ( Suddenly I could afford 'em! )
Stopped again, hard times.
Started again, good times.
I Don't remember the t206 rare backs being so popular. Maybe I was not paying close enough attention. I bet collecting a set is fun, but have they always drawn high dollars like that?
