Hello I am curious my son found a coin at school and I am trying to find some information on it and have been unsuccessful. I think the date is 1721 on the side with the date there is a man with what looks like a crown and possibly something around his neck. On the other side there is what seems to be a ship with 3 sail but no writing. I would really appreciate if anyone can help me out? I am not sure if I should look into this more or if this is nothing. Thank You
