Jimmy,
I
absolutely would not have bought as many modern baseball cards as I did during the late 1980's and early 1990's!
As all of us have known for quite awhile, because of the quantities produced they are virtually worthless. I actually came to this realization in the the mid-late 1990's and donated the great majority of them to charity and used them as a tax write off.
The idea about streamlining the focus of your hobby and selecting quality pieces over quantity is a solid one and I believe most of us could really benefit from following this strategy.
