i have found a coin copyrighted thru the Franklin mint and cant find out anything about it. i have called the franklin mint several times and determined that the people that work there are unaware that they make coins. all they want to do is sell you more or send you to websites that want to sell you more. the coin has william clark (lewis and clark expedition) bust cap facing right with a transom on the reverse. does anyone have a clue what it is made of? the coin is very malleable.
