What This Coin Looks Like (Obverse, Reverse, Mint Mark Location, Special Features, etc.): One major variety is the 1844/81 Braided Hair Large Cent (Penny) Overdate error. This coin features the 1844 date struck on top of an inverted or upside-down 1844 date. This can be identified by noticing parts of the underlying "81" being seen under the overlying "44" at the end of the date. In some cases a very small portion of a "4" can be seen under the "8". These features are depicted by the arrows in the example image of the coin above.
