My sweeties parents have been visiting Las Vegas for many years and usually do so a couple of times each year.
They have been collecting these silver strikes since they first introduced in casinos and now they have a very large collection of these coins.
I was allowed to see these coins and they really are a site to see. They of course have the name of the casino on the coins, the worth of each silver strike and a picture as well on both the front and back of the coins.
Some of the silver strikes that they have collected are from casinos which are no longer around anymore. I don't know if these coins are worth more than face value or less now, but who knows maybe in a few years they will be worth much more to a collector.
They simply saved these silver stirkes as a momento of their trips to Vegas and they really are neat to see.
Here is some more information on these silver strikes that you may enjoy reading about.
