What Drives This Coin's Value
Primarily influenced by condition; because it is extremely common and has been demonetized, it holds very little financial value unless in pristine Mint State.
Similar Coins
Can be confused with other Cupro-Nickel Mexican coins of the 1980s, but the unique profile of Coyolxauhqui is very distinctive compared to the more common Jose Maria Morelos or Cuauhtemoc designs.
Authenticity & Counterfeit Red Flags
Check for crispness in the Aztec-style border and the weight; counterfeits are rare due to the coin's low market value.
Notable Varieties & Errors
There are no major recognized varieties for the 1983 issue; most collectors focus on obtaining a high-grade example with original luster.
