Peru 1755-L JM 1/2 real
This specimen is one of a series struck 1751-60 during the reign of Ferdinand VI (1746-59). There are five varieties for the year, including a change of assayer initials from JD to JM. This indicates a switch to a different secondary assayer by the name of Manuel Iglesias Abarca. The variety shown is of the JM type, thus it was struck later in the year. It is considered very rare by Gilboy. As a class, colonial coinage of Peru is much less plentiful than that of Mexico, tho it is more available than the remaining mints. However, Harris noted only one-fifth as many Peruvian half reales of Charles III as that of Mexico, so it can generally be said that these fractionals are scarce.
