1/2 Real - Carlos IV Numeral IIII

Carlos IV's numeral on these coins reads "IIII" rather than "IV" — a deliberate archaism rooted in Spanish royal minting convention that predates the reign itself. The Lima mint operated under the same ordinances governing all colonial mints in Spanish America, but output from Lima carried particular strategic weight: Peruvian silver was the financial backbone of the entire colonial system, and the half real was the lowest denomination through which that system reached ordinary daily commerce.

The long production window of 1791–1808 ends precisely at the point Spanish colonial authority began fracturing under Napoleonic pressure — Carlos IV abdicated in favor of Ferdinand VII in March 1808.
