Last week, I had posted about a large amount of George Washington presidential dollar coins that were not stamped with "In God We Trust" and mistakenly made it into circulation.  Although the first coin found was bought for $600, the coins became so common that the price tag for these unstamped coins lowered to approximately $50 each -- Still not shabby.

Imagine the excitement of Mary and Ray Smith, a Colorado couple, when they discovered a presidential coin without a heads or tails.

The couple, who live in Fort Collins north of Denver and collect coins, bought two rolls of the presidential dollars March 7 after hearing about the earlier mistake. Mary Smith said she thought they might find a "Godless" dollar of their own.

The faceless dollar could be worth thousands of dollars, maybe more, Guth said. The value will depend on how many similar misprints are found, but the Smiths' will always be worth more because it will be the first one independently authenticated, he said.
