Stack's Bowers June 2026 World Premier Collectors Choice Auction, part of lot 72265

This specimen was part of lot 72265 in Stack's Bowers June 2026 World Premier Collectors Choice Auction (Costa Mesa, CA, June 2026), which sold for $561.20. The catalog description^[1] noted, "MEXICO. Group of 1/2 Reales (18 Pieces), 1826-62. Zacatecas Mint. Grade Range: EF Details to VF Details. A group of mixed date 1/2 Reales with various conditions and wear. From the Kirk Menczer Collection of Republican Reales Minors." This specimen was struck at the Zacatecas mint in 1842, one of a type struck there 1826-63 and 1869. The larger denominations of this mint show the "Z^S" mintmark but this one uses a simple "Z". Assayer OM (Manuel Ochoa and Manuel Miner) is listed for 1831-56. The SCWC lists the 1842 as a common date, which it probably isn't, along with an 1842/1 overdate.

Recorded mintage: unknown.

Specification: 1.69 g, 0.903 fine silver, .049 troy oz ASW.

Catalog reference: KM-370.11.
