The reverse of a Crown-piece, enamelled in six colours, the parent coin gilt and the lettering and other details picked out in gilt, brooch mounted.
 
Extremely fine.
 
Note:  The quality of the enamelling is superb, and it suggests that it is the work of Edwin Steele of 7 Regent Parade, Birmingham.  Alas the scan really does not do justice to the depth and richness of the colours.
