Guy only has a starting bid of five bucks. There looks to be a 5 lire in there. Because it looks to be the same size as the cartwheel. The 5 lire is 25 grams of 900 silver. http://www.ebay.com/itm/coins-mix-c...37?pt=Coins_US_Individual&hash=item1c2e81ef55
That same design was used on a 1 gram .835 silver coin as well, there's no way of telling what size it is.
