What dimes are worth money?

The answer to this question is a curiOSity. A dime bought and sold by a John Feigenbaum the President of David Lawrence rare coins had a value of 1.9 million dollars in 2007. The dime is a dime struck in 1894 in San Francisco. What's unique about this coin is that in 1894, the United States Mint struck coins in Philadelphia, New Orleans and San Francisco. And in the year prior and the years hence, they struck dimes, quarters and half-dollars at all of those mints, however in that year they only made 24 dimes at San Francisco. The theory is that visiting dignitaries each received 3 dimes and the mint head took three however there is no proof of that. In the seventies a reporter who worked with a coin collecting magazine heard from the daughter of the minter who told him that she was given the three dimes and told to hold onto them until she was much older as they would be worth a lot of money. The daughter also said that the dimes were given to prominent bankers who were visiting the mint. Their names and history are unknown. 9 still circulate the ice cream dime was the one that Hallie the minter's daughter had used to buy ice cream, the Eliasburg dime was sold at auction in 2005 at 1,050,000 dollars and resold by Feigenbaum for 1.9 million in 2007. At the rate of exchange and if coins continued to gain in value at this speed, the Eliasburg dime would be worth 2.5 million dollars in 2010. So there is no dime worth a million dollars it is now worth 2 million.
