have bought a lot of Swiss cantons coins a couple of months ago, and only now found some time to go through of them. Please have a look at the below coins, I assume the one on the right to be genuine one, and the one on the left to be "strange" Both have correct diameters, lettering and alignment. The one on the right weights 1.68 gr and the one on the left weights 1.48 gr. Numista says must weigh 1.84 gr and I haven't found any other reference of the should be weight. The one on the left is very slim, and when dropped or contact with other coin has a very strange sound, like tin or non metal at all, also if you try to bend can be bent, while the one on the right has nice solid sound when dropped, wouldn't bend and is thicker than the left one.
What do you think the left one is a fake? Or mint error, using bad planchets? If fake, could it be "fals d'epoque" or modern fake?

I was going to sell the left one, but realized the differences and ended the listing. Also note differences on the obverse pictures from the NGC one and Numista one, in particular the shield that holds inside the bear, in Numista the shield is linked with its other parts with dots, while on NGC the shields parts are linked with lines, both my coins are like the NGC one. Would really appreciate any thoughts, especially of those who own this type of coin or have experience in Swiss Cantons coins.
