Stop in for a cup of coffee

One of my EEs used to collect them. I used to snicker to myself every time he talked about going to card shows. Then he bought a house with his card profits, never snickered again!
He's shown me his storage bins full of cards he must have a few thousand mostly all graded cards. He got older and like most moved away from home. His dad continued to collect and sell and when he passed, he gave the collection to my buddy. The values of baseball cards have increased over 50% in the past three years. He sold a few singles last month 1960's cards and made 6K for just posting them.
