System errors have crept into the US Mint and resulted in $1.00 coins without the familiar "In God we Trust" wording being issued.
Authorities don't know how many of the coins have been released into circulation, but they are part of a 300-million run.
"The US Mint has struck more than 300-million George Washington Presidential $1.00 coins," reads a statement from the US Mint.
" We have recently learned that an unspecified quantity of these coins inadvertently left the United States Mint at Philadelphia without edge-lettering on them. It is unknown how many of these coins without inscriptions on the edge have been placed into circulation."
At least some of the coins were produced with the edge lettering bearing the inscriptions “In God We Trust” and “E Pluribus Unum,” as well as the mint mark and year.
"We take this matter seriously. We also consider quality control a high priority. The agency is looking into the matter to determine a possible cause in the manufacturing process," the statement continues.
"Production of the Presidential $1.00 coin, with its unique edge-lettering, is a new, complex, high volume manufacturing system, and the United States Mint is determined to make technical adjustments to perfect the process. As we adjust this new process, we intend to eliminate any such defects."
Along with stamps, faulty coins are highly collectable and one of the new coins have already sold on eBay for $405.00.
