1 Centavo Aluminium Piedfort

Piedforts — coins struck on blanks double or more the standard thickness — were produced almost exclusively as presentation or pattern pieces, never intended for circulation. Nicaragua's 1892 aluminum piedfort exists at the intersection of two curiosities: aluminum was still a prestige metal in the early 1890s, only recently made affordable by the Hall-Héroult electrolytic process patented in 1886, and Nicaragua was simultaneously navigating the monetary reforms that accompanied its broader engagement with Central American currency standardization. A piedfort in aluminum at this date is an unusual combination of material and format.

KM#P6 designations cover pattern issues, and surviving examples are typically traceable to a handful of specimens.
