My kids found this coin in Prince Edward Island a couple of years ago. We didn't know anything about geocaching until we went to the PEI Winter Woodlot tour in Brookvale last Saturday. There was a booth there about geocaching and we saw a similar coin and asked about it. Once they explained how it works, we looked up the coin online and saw it belongs to someone else.
Not sure what to do next, maybe we'll hide it??
