Collectable Counterfeit Coin Made Before 1844

Do you have pictures of the coin?

Interesting forgery it appears. The side with the Queen's portrait has most of the clues to detect the forgery and to classify the type. If you compare the two coins, the 2002 has a wider rim with a depressed area between the edge of the coin and the edge of the design field. This looks like an impact transfer die. The outer edge of the coin rises sharply above the coin's surface - I would check to see if that is caused by the edging process. The edge was most likely applied after the coin was made not at the same time. The fields look very rough and the design is "fuzzy" - both of these features are common on transfer dies. There is a suspicious lump below the T in the Queen's name.
