The 5 pesos gold coin was sporadically issued from 1905 to 1920 and reissued in 1955. The 5 pesos gold coin was issued for circulation using the bust image of Independence War hero Hidalgo.
It is often assumed that the silver 5 pesos coin minted from 1951 to 1957 was the first coin to bear Hidalgo's image but the 5 pesos gold coin came first and it is an honest mistake as collectors of gold coinage are smaller than that of silver and base metal coinage collectors.
The obverse design features the Mexican coat of arms, an eagle clutching a snake while it perches on a prickly pear cactus. On the outer periphery is the phrase “ESTADOS UNIDOS MEXICANOS” or as translated to english “United Mexican States”.
The reverse design features a bust image of Hidalgo facing left. On the outer periphery is the denomination "CINCO PESOS” and year of issue. Just below the bust design is the mint mark “M” for the Mexico City Mint.
