Observations from a yard sale - 80s/90s junk cards

[swarmee]

For those of you criticizing the junk wax buyer, they could just know more than you. There are approximately 15 cards in 1990 Topps that sell for $500-1,000 each if they have a specific rare print defect. There are four or so better known errors in 1991 Topps that regularly sell $100-200 each if you know what to look for.

If all you see is a monster box of commons from Topps junk wax era, and you're not screening them for these rare errors/variations, then maybe you're selling the boxes cheap...

Same thing for modern Topps or Heritage or Upper Deck. So many unannounced/nearly impossible to notice SPs, SSPs, errors, etc that people looking to complete Master Sets still need. Before you toss them in the trash or sell for cardboard recycling value, check your cards against junkwaxgems or baseballcardpedia.
