Stack's Bowers June 2026 World Premier Collectors Choice Auction, lot 72245

This specimen was lot 72245 in Stack's Bowers June 2026 World Premier Collectors Choice Auction (Costa Mesa, CA, June 2026), where it sold for $585.60. The catalog description^[1] noted, "MEXICO. 1/2 Real, 1829-Z AO. Zacatecas Mint. NGC MS-62. Third finest of only three graded by NGC. Nice dark tone, well struck. From the Kirk Menczer Collection of Republican Reales Minors." Zacatecas and Guanajuato were the two mints that made a serious effort to produce minor coinage for local use; the other mints preferred to concentrate on striking eight reales for export. Zacatecas half reales are known for 1826-63 and 1869 and this is a common date. Assayer AO served 1826-29. Assayer OV is known for 1829 two and eight reales but doesn't seem to have stamped half reales. Most of the early half reales have a simple "Z" mintmark.

Recorded mintage: unknown.

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

Catalog reference: KM-370.11.
