Un dolar valorează cinci milioane de dolari. Ce are special?

For one Texas coin collector, a dollar could be worth millions.
It's a 1794 Silver Dollar -- one of the few remaining from the country's very first batch of dollars -- and when it goes up for auction in New York City on September 30, it's expected to sell for between $3 million and $5 million.
There are only 150 of the coins known to exist, and this is one of the three best preserved; it's the kind of thing coin connoisseurs dream about.
John Kraljevich, a consultant for the auction house Stack's Bowers that's handling the sale, said the coin's historical significance has collectors craving it.
