This bug is missing from the cache. The attached info sheet (with the tracking number) was in the cache, but there was not a coin in it. The last written log entry was on July 21, 2007 when the previous carrier placed it in the cache. I looked all around the cache and even dug through the area but I could not find the coin itself.
I recommend removing the coin from inventory until it can be found otherwise people, such as myself, may go looking for something that does not exist. Sorry.
