Found the virtual cache on my birthday while walking around the Quarter with a good friend. Messaged coin owner, hope to discover the coin.
It's a shame almost all coins soon vanish from caches now. When I first started caching in 2008, it was common to find them. Almost all of mine came up missing long ago, though, and i would no longer risk putting an actual coin in a cache. Great idea to have a virtual coin in this virtual cache.
