Your coin is NOT is "The Doctor Inn on Bryant Lake" - GC15XXP
It has disappeared between 9/21/2007 and 1/11/2008.
There have been a lot of people who have found the cache since it was dropped on 9/21/2007, so you may never know who picked it up.
You might want to contact Tuxedo Duck as he logged that he discovered the coin on 10/7/2007, which should not be possible as he has never found the cache that the coin was supposed to be in at the time.
Sorry!
