I played the Cal-Neva machine yesterday and all silver dollars were from 2005 and 2006. They say they are one ounce fine silver but a $1 value. If actually currency why would they make a silver coin with a value less than the price of silver? I am probably missing something. The machine is interesting as it is brand new but has no markings as who made it. It has buttons for max credits even though you can only play one line with a quarter and it only accepts quarters. It also has a well-made homemade display of wood and lots of the coins. It is pretty fun, though I would think IGT would have something to say about it.
