So.... When I got home from my trip through the Midwest two years ago, this coin was nowhere to be found. I couldn't understand it - I knew that I had put it into my suitcase. I looked through all my stuff, but it was gone. I felt bad about it and sent a message to the owner, but didn't mark it as missing, just in case it showed up.
Two years later - just last week - I was packing for a trip. I opened up my suitcase, and there it was! It had apparently spent the past two years stuck in the suitcase's lining, and had finally slipped out.
So now it has a new home, closer to the AT. I hope someone moves it along soon.
