1974-Mo Mexico 20C Copper PCGS MS66RB $190

Updated August 20, 2026

1974-Mo Mexico 20C Copper PCGS MS66RB $190 This exceptional 1974 Mexico 20 Centavos is a premium specimen struck at the historic Mexico City Mint (Mo) and authenticated by PCGS with a high Mint State 66 Red-Brown (MS66RB) grade. Representing the iconic Madero design series, the coin features the national coat of arms on the obverse-a golden eagle perched on a cactus devouring a serpent-while the reverse showcases the portrait of revolutionary leader Francisco I. Madero. This specific piece is highly desirable for its stunning preservation, retaining a significant portion of its original mint luster and vibrant copper warmth alongside a delicate, developing patina. As a high-grade survivor from the mid-1970s, it serves as a cornerstone piece for collectors of Mexican numismatics or those building a registry set, offering a rare combination of technical perfection and visual character. At $190, it represents a sophisticated acquisition of 20th-century Mexican coinage in a state of preservation seldom seen in general circulation. Condition: This 1974 Mexico 20 Centavos is in Mint State condition, specifically graded MS66RB by PCGS, indicating a high-quality strike with minimal surface marks and significant original luster. The "RB" designation signifies Red-Brown, meaning the coin retains between 5% and 95% of its original red copper color alongside natural toning. The mint is the Mexico City Mint, identified by the "Mo" mint mark. The metal content consists of a copper alloy (95% copper, 5% zinc/tin), which was the standard for this "Pirámide del Sol" (Pyramid of the Sun) design series. Historically, this coin belongs to the final years of this specific 20 centavos design before the effects of inflation led to significant changes in Mexican coinage denominations and sizes. As a business strike (Regular Strike) rather than a proof, finding examples in this high-grade MS66 tier is challenging, contributing to its collector value. While common in circulated grades, the PCGS certification and high numerical grade justify a premium price, though the $190 asking price is significantly higher than the $95 retail estimate shown on the dealer's label, suggesting it is priced for a specialized registry set collector.
