The coins listed here must have some special characteristics in order to be considered collectors' pieces; that is, they should be a higher grade (condition) than the average, they may be scarce or rare dates, or they may simply be in greater demand than the supply. We offer in this section Mexican coins from all historical periods (Viceroyalty, War of Independence, Empires of Iturbide and Maximilian, Decimal and Reales Systems of the XIX century, coinage of the Twentieth century and of the Revolution).
