||1820 50C Square Base Knob 2, Large Date MS61 NGC. O-104, High R.4. Ex: "Col." E.H.R. Green. The 1820 O-104 is rare in all grades. High grade examples are especially difficult to find. The Newman coin has untoned centers and a thin band of golden-brown toning through the stars and legend. The coin was gently wiped, modestly reducing the impact of its cartwheel luster. The bold strike is quite impressive. Ex: "Colonel" E.H.R. Green; Green Estate; Partnership of Eric P. Newman / B.G. Johnson d.b.a. St. Louis Stamp & Coin Co.; Eric P. Newman @ $3.50; Eric P. Newman Numismatic Education Society.
