The 1892 date ties this piece directly to the wave of Columbus Quincentenary coinage produced across Latin America that year, though El Salvador's regular silver 50 centavos issue ultimately took a different path to production. Pattern coinage from the Central American Mint at San Salvador is poorly documented in the standard references, and KM#Pn14 accounts for almost nothing beyond the bare attribution — which itself suggests very few examples were examined when the type was cataloged.
Copper at this weight was almost certainly a die trial rather than a serious denomination proposal.
