This coin was produced to help raise money for the Estonian Mage that took place in 2016, we have a few left and a percetage will still go towards Geocaching activities here in Estonia.
The idea for the front of the coin can from a famous photo take during the winter, blue sky, black treeline and white snow, this is also the Estonian flag. In the center you can see the Tallinn TV tower wich is visble for miles around.
