A favorite of mine, I own one but unfortunately I'm on vacation and don't have any pictures, so have a stock photo from numista.
It's a copper Commemorative coin weighting about 5 grams, with a diameter of 25mm, a face value of 0.05 Italian Lire.
A 1908 specimen in VF costs about 40 euros, when bought with warranty from a coin shop and directly in Italy.
