Both are very clean and in good shape. Q*bert has some actiplaque on the stickers and a small tear on the marquee decal but that's it. Frogger is very clean and doesn't have any major damage. No battery covers included but I've used the cover from a Donkey Kong tabletop on Frogger, so all Coleco covers are interchangeable I believe. Don't know about the Q*bert since it's the only Parker Bros. game I had.
Asking $25 + ship for Frogger and $20 + ship for Q*bert. Or take both for $40 shipped.
*EDIT* just noticed that there's small crack on the Frogger screen that wasn't there when I took the pics. Most likely my little nephew did it. Dropped the price on Frogger because of this.
