Mexico G91-3060r.jpg

This specimen was lot 3060 in Goldberg sale 91 (Los Angeles, June 2016), where it sold for $64.62. The catalog description[1] noted, "Mexico. 50 Centavos, 1907-M NGC MS65. Curved 7. NGC graded MS-65." This specimen is a common date of a series struck 1905-18 at the Mexico City mint. "Curved 7" and "Straight 7" varieties exist but are priced the same. It is claimed that one variety was struck in Mexico City and the other under contract in Birmingham, England but no one has been able to establish which was which. This fifty centavos piece replaced the fifty centavo piece struck 1869-95 under the Republic. The older coin was 13.54 g, .903 fine. It, in turn, was replaced by a smaller fifty centavos piece in 1919. The last branch mints, Zacatecas and Culiacan, were closed in 1905 and all official Mexican coinage since has borne the Mexico City mintmark ("M" or "Mo").

Recorded mintage: 18,920,000 with straight 7 plus 14,841,000 with curved 7.

Specification: 12.5 g, .800 fine silver, .321 troy oz ASW.

Catalog reference: KM 445.
