Last week mexican mint released 6 new coins, all of them commemoratives, however, beetween the 3 new 20 peso coin, one of them caught my attention, the new 20 peso coin commemorative the 500 years of Tenochtitlán memory.


As you can see, this is a new coin design in my country, because reverse side of the coin has 2 views, like a mirror effect. One side project the old piramide de Tenochtitlan and the other one the Mexican cathedral. I would like to know if this kind of coins has a name? I just called "mirror coins" and most interests Do you know other coins like these? I would love to see them. Best Regards!
