Ok, I'll start:

Passed up a boxed original Genesis cause the lady wanted $15 and the box had some damage. Not worth it. But at the next sale:

$2 each:
Galaxian handheld Coleco mini-arcade unit
Pac-Man handheld Coleco mini-arcade unit

Yay! I've never found these in the wild before! Both are a bit dirty, and neither has perfect stickers (the marquee stickers on both are torn too ) But they seem like they'll work (haven't tested em yet)! Did I do good?
