For a commentary on the Guadalupe y Calvo half escudo, see here. The mint used two pairs of dies. The first die pair was used from 1846 to 1848. The obverse used a Mexican facing eagle style, and the dies were likely made at the Soho mint in England. The second pair with a larger Sonora eagle were likely made in England and probably at the Soho mint. They were used in 1850 and 1851. This pair of dies were transferred to Culiacán mint and were first used there in 1854.
