1806 Knob 6, No Stem

The Knob 6, No Stem combination pairs two distinct die changes that happen to share a small subset of 1806 die marriages. The Knob 6 obverse uses a date punch where the top of the 6 finishes as a rounded knob rather than a sharp point, and the No Stem reverse is exactly what it sounds like: the bottom of the olive branch in the eagle's claw ends without the terminal stem that appears on most 1806 reverses. The combined Heraldic Eagle production for 1806 ran to 839,576 pieces, and within that figure the Knob 6, No Stem is a definite minority but not strongly premium relative to the Pointed 6 with Stem. Overton catalogues the marriages individually; the variety attribution here treats the two diagnostic features as the searchable pair.

The most useful authentication checkpoint is the bottom of the wreath itself. The terminal stem is a clear, raised line below the bow; its absence is unambiguous and not a die-state issue. Be wary of examples where the stem appears to have been tooled away on a worn coin, since this kind of post-Mint alteration is one of the recurring frauds on early halves. Edge lettering FIFTY CENTS OR HALF A DOLLAR must be intact, weight should hold near 13.48 grams, and PCGS or NGC certification with the variety noted on the holder label is the practical floor for any premium price. Adjustment marks running across the obverse are typical of 1806 planchet preparation and should not be confused with damage.

Collector demand for the Knob 6, No Stem skews toward specialists who are working an Overton set or filling the variety slot in a 1806 subseries. Generalists buying one 1806 for a Draped Bust type set almost always default to the Pointed 6, Stem since it costs less and appears more often, which keeps pressure off the No Stem in mid grades. Examples in VG through Fine appear at every major auction, AU coins are scarcer than for the dominant variety, and choice Mint State pieces are decidedly thin. Premiums on attributed slabs tend to widen at the upper end.
