One particularly interesting and extremely rare variety of the 1811 Classic Head Half Cent (Penny) is the unofficial restrike featuring the reverse of 1802. This coin was not struck by the US Mint. Instead a man named Joseph J. Mickley privately struck the coins using muled dies. Mickley obtained the dies when the US Mint sold him the broken rusted dies as scrap metal in 1816. Using muling (combining different coin dies that were never meant to be together) - Mickely used a rusted 1811 obverse die with a rusted 1802 reverse die to produce lower quality restrikes. Only about 12 or so were estimated to have been produced.
