While searching for information about the "EarthCache 1st International Mega Event Coin" I found the tracking code of this coin in the photo and I hope that the log entry will be accepted.
For almost three years I have been trying to find out the history of old geocoins and am creating an online project entitled "Little stories from the first geocoin years" (http://www.khstreiter.de/cachen/alte_coin.htm).
Warm regards from Compubaer from Germany.
