I recently made a trade and was able to get 7 casino silver rounds. Like the one below which is one of the 7 different casinos. These came out in 1973 and some in 1974. I know this only because they are dated. Wanted to know if anyone might have a complete list of what was put out back then ? I also would like any sort of an idea as for rough values on these as they have now been saved through two big rises in silver melting periods in time. If you might also know the mintage's that would be of great help too. they do say .999 fine silver on the outer rims. Some say so on the obverse sides.
