A send-off for the American penny. Three ledger books in coppers' stages of wear — Uncirculated, Aged and Tarnished — each back embossed with one of the coin's obverse designs: the wheat stalks, the Lincoln Memorial, and the Great Seal.
Inside, copper rules with faint mint ledger columns, so it keeps a column of figures as readily as a paragraph. From Chicago's Field Notes. Sold as a 3-pack.
