Hello, dear friend! Thank you very much for your answer. This jeton came with the bunch of russian medals and tokens, mainly commemorative. There was one prussian medal- red eagle medal, you can see it on german section of this forum. There is nothing on the back of this jeton. Unfortunately I do not know their history, and I sold some of them due to lack of money, maybe it's a mistake. Thank you. Mummytrol:).
