Allsong, I'm sorry to say, but any seller who is lazy enough to post one picture for multiple items is a seller to avoid. When I buy on the bay, I am buying the coin that I see in the picture, plain and simple. You should have heeded the warning that he gave you right in the description, about "you might not get the coin pictured" but hey, live and learn.
The price of shipping this coin back to him is not a waste of money in my opinion. Rather it will serve to remind you to be dilligent when you are buying. Hope you settled the matter after all.
