Aluminum. Plain Edge. A rare and seldom offered pattern issue, the present coin has a planchet flaw which extends up from the rim left of the date into the field before Liberty's face. Aluminum as a planchet metal was seldom used and the mint workers were not regularly handling this somewhat exotic choice for coinage, hence the trouble with the present planchet. Highly reflective fields otherwise with watery depth and free of toning. The devices show considerable frost. One of perhaps half a dozen known in all. The obverse is the regular dies of the issue, while the reverse is an effort to correct the lack of the word "CENTS" on that side, with CENTS spanning the large central V on a ribbon.
