|It's a mysterious US nickel that was estimated to bring $2.5 million at auction. The coin, known as the Walton nickel, surpassed estimates and sold for $3.17 million in early 2013.|
|This nickel is both old and rare, one of only five that were struck at the U.S. Mint in Philadelphia in 1913. That year a buffalo image was to replace the Liberty head design on the front side of the U.S. nickel. Five coins were inadvertently struck with the old image.|
The coin is not supposed to exist. It is supposed to have the buffalo design.
|A decade ago, as a promotion for a display of the other four nickels in the set, a $1 million reward was offered for anyone who brought in the missing coin. Walton's family decided to bring their nickel in to see if it might be real after all. Indeed it was. |
The family decided to put the coin up for auction. "It's been in their family for 70 years. They decided that the hundredth anniversary of the coin was the right time to sell it and for another collector to have it.
