I have been collecting pennies for quite a while and people often give me any they find .But i have been given this by my sister who found it in her aunts house.I ahve looked everywhere on the net to find out what it is and had no look.Ever William and Mary coin i look at does not have the same sheild on it.Or the 40s on reverse.I presume this means 40 shillings.Can anyone help ....Thankyou
