Hi everyone. I'm very new to coin collecting, a couple of days almost but its surprising what you can find. So, short story very quickly. I was given some change the other day and when I tipped out my pocket I found a very worn old looking coin, could of passed for a 10p, well, it did to me. So I told a friend, he looked and said I should check online to see what it was, but I told my mum also and she gave me three other coins she's had, again, very interesting but i'm at that point where I need some help clarifying what these coins are. I think I have a William III Shilling 1699 A George III silver Crown 1819 GEORGE III HALF PENNY 1807 ELIZABETH II DEI GRATIA REGINA 1965 CHURCHILL I do have images I can link to if anyone could help, many thanks.
