4 Reales Type V Countermark

El Salvador's countermarking program of the 1860s was a practical response to chronic coin shortages in a newly independent state with no established mint. Rather than striking original coinage, the government authenticated foreign silver — predominantly Spanish colonial and South American republican issues — by punching official marks into circulation. The Type V punch applied to this 4 Reales host was part of a series of successive countermark types that numismatists have spent considerable effort sequencing, with KM#68 representing one of the later validations in that progression.

The host coin's origin matters as much as the countermark itself for establishing value and rarity.
