A US numismatic error consisting of a Type II blank planchet intended for a small cent, likely a Lincoln cent. The planchet is composed of a copper alloy and features an upset, raised rim, indicating it has passed through a milling machine but has not been struck by dies. Both the obverse and reverse surfaces are blank. The metal displays a dark brown, aged patina with mottled toning and areas of surface spotting. The item is housed in a vintage 2x2 cardboard and plastic flip. The front of the holder is labeled BLANK PLANCHET in red ink. The reverse of the holder features a printed dealer mark for KENNETH M. ENGLUND Coins & Stamps of Brainerd, Minnesota, and includes a handwritten code BHNN in blue ink. The planchet shows significant dark brown environmental toning and oxidation across both surfaces. Mottled toning and spotting are evident. Minor handling marks are visible under magnification. The vintage holder exhibits age-appropriate yellowing and wear.
