This specimen was lot 40283 in Ponterio sale 168 (Philadelphia, August 2012), where it sold for $2,232. The catalog description[1] noted, "MEXICO. 20 Pesos, 1871-Zs H. PCGS Genuine--Scratches, VF Details Secure Holder. VERY RARE type." This expensive type would be even rarer were it not that many examples were hoarded as Mexican silver became overvalued. Finally, in 1905, the Diaz regime devalued the silver peso 50% and issued a new series of gold coins half the weight of their predecessors. Mintage figures are not a reliable indicator of rarity for this type due to the accidents of hoarding; many low mintage issues are readily available while other high mintage issues are very rare.

Recorded mintage: 1,000.

Specification: 33.84 g, .875 fine gold, .952 troy oz AGW.

Catalog reference: Fr-127; KM-414.8.
