The 1806 O-108 Half Dollar
David Lange of Numismatic Guaranty Corporation writes:

1806 KNOB 6 NO STEM O-108 50C MS
NGC Attribution: O-108

Diagnostics
Overton's Obverse 4 was used in three die marriages, the most notable of which is the present one. O-108 pairs this die with Reverse F, which is one of two "No Stem" dies for the date and is unique to this marriage.

Comments
Unlike the common O-109, which features a "No Stem" reverse and a Pointed 6 obverse, this very rare (R-7) die marriage is distinctive for its "Knobbed 6" date.
