I think there might be a couple people on the site that have bought these before, but it's not something that we've officially tracked.
I saved one misc auction back in Oct of 2009 that included a 1983 green plastic bordered puzzle with a modified version of the Elmore art on the red box cover (it just features the dragon on the puzzle). There were 5 AD&D
1e books and a couple modules as well, with the whole lot selling for $21. I'm not sure if the auction went under everyone's radar, or just that those puzzles aren't too sought after. I'm tending to think along the lines of the latter.
edit: I missed this one from several months back for 2 puzzles at $49 total.
