I found an entry in the logbook of the geocacher who took the coin to move along but did not log it out of the cache (or even log the cache find itself). It reads "11/4/08 Election Day Best day for caching, 20's, light breeze, perfect. We'll move Firesafe 23 coin along. TFTC. Husker, Willie, and Whopper". I've attached a photo of the page as well. I think this coin will show up again.
