We have a dumpster site about 4 miles from home we use once a week. About a year ago there was a large antique hump back chest below a dumpster with the attendant lady standing there. She said it was too heavy to lift it up and in. She said a middle aged guy left it for trash and it belonged to his recently deceased father.
We looked inside and it was packed FULL of (drum roll...) baseball cards!!!!! All organized, many of them autographed, many in plastic with a rating seal. From what I could see a wide variety of years, some were very old.
Unfortunately we were in a car and in a hurry. If in my truck I would have loaded it and I'm not a collector.
The lady working there said she would call a collector she knew. To this day I think about I should have gone home, got the truck. Who knows what it was worth...thousands of cards.
