Baseball cards seemed to be something everybody collected. I gave my small collection to my daughter a few years ago.
The All Stars piece sounds like a great piece to own. We are a lot like you, we kept anything we ran across that we thought would increase in value. Duck decoys, Coca-Cola items, Longaberger baskets, die cast cars, paintings, Fenton glass and lots of other stuff. We have liquidated most of it in the past several years to fund our retirement years. Some things panned out and some didn't, like all investments.
