Twentieth Century (Modern)

MEXICO. Mint Error -- Off-Metal Strike on Aluminum-Bronze & Steel -- 5 Pesos, 2018-Mo. Mexico City Mint. PCGS MS-66 Gold Shield.

cf. KM-605 (for regular issue). This interesting error features a complete reversal of the metallic compositions, in that the outer ring here is composed of aluminum-bronze, and the center is composed of steel, rather than the expected other way around.

Estimate: $100.00 - $200.00
