I'm one of those guys in his 30s that has just started in the last few years to move to pre-war. I still collect 50s and 60s also. Have just about everything from the 70s and 80s.
It will be very interesting to see what collecting will look like in 20 years. Who would have thought 20 years ago that the internet would have changed collecting like it has. Stores and card shows are just about gone.
For my sake I hope the bottom falls out and I can pick up T206 HOFs for a buck.
