20 Centavos Pattern

The 1892 date places this piece squarely within El Salvador's numismatic experimentation leading up to the country's adoption of the peso system, when the Central American Mint in San Salvador was producing multiple pattern proposals in varying metals to evaluate designs before committing to production coinage. Copper patterns of this denomination are seldom encountered, suggesting the striking was minimal and almost certainly never left official hands.

KM#Pn12 is among a small cluster of 1892 patterns from this mint, most of which differ by metal or die pairing rather than design revision.
