Hi guys, I hope I have found the correct section to post this.
While out riding and building some BMX jumps (I'm 15 years old) I found a green coin in the ground, looked the diametre of a normal 10c coin but I thought I may as well pick it up and pocket it. There was nothing which I could see visually to determine what coin it was so I went home and scrubbed off the green stuff of it and after wards I later found it was a 88 year old 1919 Half Penny. My question is, is it worth anything especially in this condition.
Here are some pictures.
