What this coin looks like (obverse, reverse, mint mark location, special features, etc.):
One major variety includes the 1807/6 Draped Bust Large Cent (Penny) overdate error - with a large "7" and pointed "1". This coin features an 1807 date struck over an 1806 date which resulted in parts of the underlying "6" being very clearly seen under and around the "7". The number "7" is also larger than the "small 7" variety. The tip of the "1" in the 1807 date is also pointed at the tip. The difference between the small 7 vs large 7 (and pointed 1 vs blunt 1) can be seen in the example comparison image below:
