PHILADELPHIA (AP) _ It looks like the U.S. Mint has struck again _ or not struck again, depending on how you look at it.
New dollar coins featuring John Adams are missing edge inscriptions including ``In God We Trust,'' according to the Professional Coin Grading Service, a rare coin authentication company based in Newport Beach, Calif.
The company said people have found hundreds of Adams dollar coins without the edge lettering, repeating a previous mistake. In March, an unknown number of George Washington dollar coins were struck at the Philadelphia Mint without ``In God We Trust,'' ``E Pluribus Unum,'' and the year and mint mark inscribed on the edge.
A spokeswoman for the U.S. Mint said the agency is looking into the reports.
After the Washington ``godless dollars'' were discovered, the Mint pledged to more closely monitor the striking process.
But a Detroit collector received smooth-edged Adams dollars in sealed containers from the Philadelphia Mint. There also are reports of the opposite problem _ Adams coins with edge lettering that has been double-struck, said Ron Guth, president of the Professional Coin Grading Service.
``It's too early to put a final price tag on the collector value of Adams presidential dollar errors because no one knows how many others will turn up,'' Guth said in a news release.
The Adams dollars, officially released into circulation May 17, are the second in a series of presidential coins slated to run until 2016.
