I did some research on this token, and in case there may be someone who is interested, and would like to know more about it here goes.
Although not marked as such, it is considered to be a half penny token. It has the image of Norwich Castle on one side and a hanging sheep on the other side, with the date 1794 in Roman numerals.
The present keep of the castle was built in 1120 and was used as a Royal Palace. From 1220-1887 it was used as a jail. Today it is a museum and art gallery.
When tradesmen began issuing tokens in the 17th century they used images that were easily identifiable as signs of their trade. The image of a hanging sheep or fleece was a symbol for traders in wool.
Generally identified as a Condor token (cataloger James Condor) these came into existence out of necessity when the British government in 1775 ceased production of regular copper coinage.
There was a large market place at Norwich so the Castle and fleece were natural images for a token.
