Came by to check on my cache since the last log said this coin was missing. Sure enough, it's not here. There is one name on the paper log between the cacher who dropped the coin and the one who reported it missing. Someone signed "Mary" on the paper log. I'm guessing Mary isn't a cacher and may have taken the coin. Hopefully if she did, she'll read the address on the coin and figure out how to log it.
Sorry to give you the bad news. I truly hope it turns up soon. I am marking it missing so it will no longer appear on the cache inventory.
