Hello All! I'm new to the site and need some help identifying a coin I've come across in my family collection. I'm planning on selling the collection so hence why I want to figure out if it's a legitimate coin, a fake or a medal/medallion. Just a note, the tiny writing below the portrait side reads 'Halliday.F' Thank you all! https://drive.google.com/open?id=0B2-I_xtEIVgQMHB6dUxhM09qeWp0U0ZRLXdEU0ZxR1hRaDdJ https://drive.google.com/open?id=0B2-I_xtEIVgQaG5McVVHckJLYWZLN3RKRW9ZWWVRLWpXLVI4
