A somewhat obscure issue from the Second Republic (just a two year type). Copper-nickel, only 16mm in diameter. In eschewing a depiction of the country's coat of arms, it represents a real departure from the aesthetic of other Mexican coinage. All in all, a very European looking coin, which stands to reason as supposedly that's where the planchets and dies were procured.
In the end they were not accepted by the citizenry and by 1886 the production of the more traditional large copper coins in this denomination was resumed. Despite nearly 100 million of these being struck, I don't see many of them, which leads me to wonder if large quantities were perhaps removed from circulation and melted down.
