yes It's unclear what you are asking. All American dimes dated 1966 are made of a clad "sandwich" metal with silver-colored cupronickel on the outside and a pure copper core on the inside. They don't contain any silver and there are no differences among any of the coins minted that year. Canadian dimes with the same date are made of an alloy of 80% silver and 20% copper, and similarly all are the same.
A platinum dime would be worth thousands of dollars ... except that there is no such coin. All 1964 dimes were made of 90% silver and 10% copper.
