1806 1/2C Large 6, Stems, BN VF35BN 认证号16087970, PCGS号1099

Ron Guth

1806 Half Cents are found with two different obverses: Small 6 and Large 6.  On the Small 6, the 6 of the date is completely separated from the bust; on the Large 6, the top of the 6 is embedded in the bust.  The Large 6 obverse is combined only with a With Stems reverse, resulting in the Cohen 4 variety.  This, along with the Cohen 1 (Small 6, Stemless) are the two most common varieties of the year. 

The 1806 Large 6, Stems Half Cent is relatively common in Mint State, including Brown and Red-Brown examples.  Full Red examples are known, but are extremely rare.
