There were some wild errors coins at the American Numismatic Association’s summer auctions this year, but none more striking than this deep obverse cap on an 1847 Braided hair cent, graded Mint State63 brown by Numismatic Guaranty Co.

It ranked 29th in the 2010 book 100 Greatest U.S.Error Coins.

According to the 100 greatest book, the cent would remain stuck to the reverse die for up to 15 more strikes. This could cause full brockage errors with the reverse and deepen the cap to the point that one can see why these types of errors were called ‘bottle caps.’

Due to multiple strikes, the reverse became flattened and distorted. It was one of six to eight obverse caps for this type. The coin sold for $28,800 Aug.
