Lisa - I don't belive your statemant of a "silver strike " is any coin made of silver is true, in fact you are going to upset a lot of coin collectors, myself included, NO WAY would I call my Morgan Dollars a silver strike, I think you need to go back and correct your statement.
I also think that a collector can collect what ever they choose and to heck with if it came from a machine, was traded for or just plain bought at a gift shop, Collect what you want to collect and enjoy the collection.
