Mexico.

The Mexicans use only gold and silver, and their national series is full of tragic interest, embracing, as it does, three and a half centuries of Mexican history, from Cortez to Maximilian. The “pillar dollar,” “windmill dollar,” “cast dollar” (the Mexicans are the only nation that cast money), and the “cob money” (a series so called by reason of its clumsiness), are all to be seen in this collection.
