2007 P George Washington Missing Edge Lettering Error Coin, Certified by NGC, a top grading company as MS66.
Over 300 million George Washington Presidential Dollar Coins were produced and an unspecified quantity of these coins were inadvertently printed at the Philadelphia Mint without edge-lettering on them. It is unknown how many of these coins were printed without the inscriptions on the edge, however there are many fake coins being circulated with the edge lettering personally removed.
These coins are all certified by NGC, a top grading company, as genuine Error Coins straight from the USMint.
