Mexico 1921-M 50 centavos
This specimen is a better date of a series struck 1919-45 at the Mexico City mint. This fifty centavos piece replaced the fifty centavo piece struck 1918-19. The "0.720" was added to the reverse to distinguish this type from earlier issues. The older coin was 9.06 g, .800 fine. It, in turn, was replaced by a billon fifty centavos piece in 1950. 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: 21,864,000.
Specification: 8.33 g, .720 fine silver, .193 troy oz ASW, 27 mm diameter, lettered edge.
