8 Reales - Carlos IV MVA - Royalist countermark coinage

During the insurgency period following the 1810 Hidalgo revolt, royalist authorities in New Spain countermarked existing 8 reales coinage to authenticate currency and prevent insurgent-controlled silver from circulating undetected. The MVA mark — associated with the royalist administration — served a verification function in a monetary environment where both sides were issuing or manipulating silver coinage to fund military operations.

The date range spans the entire insurgency through independence in 1821, meaning some pieces received their countermark only months before the royalist cause collapsed entirely.
