I'm in a bad card relationship, what to do...

[mintacular]

To make a long story short, I collected cards with my brother during the late 80s when cards were hot and the rookie card syndrome struck America...Since then,
we dumped most of our overproduced sets and cards ('90 UD, etc.) and only kept a few token reminders.

However, at this time I helped steer us into collecting "vintage" cards (50s 60s) including Mays, Mantle, Aaron, Clemente, 1957s (sentimental value), and a few more ...

Later, as I pursued card collecting more actively I started dabbling with pre-war and even some post-war sets and players--not just the most touted. The problem is that he is very picky about condition (so was I but I've softened) and he pretty much just appreciates recognizable issues w/major stars and rcs.

When I showed him a few T's and pics of Cobb T206s, etc. they did not seem to grab his attention. What should I do? Just accept that my card collecting interests have diverged? Have you ever collected with a a friend or family member and your interests did not align? Thanks for sharing...
