There is no "Mayas" issuing authority recognized in numismatic literature for a 2012 bimetallic 10 Centavos piece. Guatemala's circulating centavo coinage is issued by the Banco de Guatemala, while Mexico's by the Banco de México — neither issues under a "Mayas" designation. Without a verifiable issuing authority, no reliable historical or minting context can be provided.
