1800 $1 AMERICAI F15 认证号15379185, PCGS号6892

1800 $1 AMERICAI, B-19, BB-192, R.2, Fine 15 PCGS. Bowers Die State IV. A charming silver-gray example of the popular AMERICAI Guide Book variety, named after the mint-made die scratch beneath the eagle's claw. Well defined for the designated grade, and relevant marks are confined to a subtle obverse rim ding at 6:30. Ex: Long Beach Signature (Heritage, 2/2010), lot 1273.

The 1800 "AMERICAI" variety features a die flaw that mimics the letter "I" immediately following the word AMERICA on the reverse.  The flaw is not an actual letter "I", which would have been the engraver's error; rather, it is simply a flaw that looks like an I, in perhaps the most fortuitous position possible.  This is considered a major variety in the Bust Dollar series, as it is visible to the naked eye.  Two varieties (BB-191 and BB-192) comprise the entirety of this variety.  As expected, both varieties share the AMERICAI reverse, but were struck from different obverses. 

The PCGS Condition Census for this major variety features coins ranging in condition from AU-55 to MS-63, thus collectors have several high-grade options from which to choose.  The finest examples certified by PCGS (as of March 2012) are a pair of MS-63s.
