This is an interesting one dated 1854. You will note the only letters visible on the coin are 'CE'. Although this coin is the design of the British homeland penny (and half penny). The letters 'CE' point to a different denomination. So, this is a 4 pence coin produced primarily for use in British Guiana from 1838-1862. All other 4P coins have a different reverse. In this poor condition, the coin isn't worth much more than its silver weight value. Even in fine condition its only worth a few bucks (without a hole). Had it been 1853 or 1852 it would be worth hundreds.
