1820 50C Sq. 2, Lg Date, No Knob AU58 认证号43607888, PCGS号6123

O-108 (108.1), from Sheridan Downey's Beaver Falls offering in March 2022, "A gossamer veil of gold toning suggests storage in a kraft envelope. Semi-prooflike surfaces, esp. the reverse, are a plus. Well struck. Nifty coin for your date or Red Book set. From Bowers & Ruddy's Jan. 14-17, 1981 sale of the Dr. W. James MacFarland Collection, lot 577 with tag."

Several interesting varieties comprise the 1820 Half Dollars, determined by the base of the 2, whether the 2 ends in a point or a knob, whether the coin is an overdate, and whether the date is small or large.  The result is five major varieties in some combination of the preceding, plus quite a few individual die varieties that require closer examination.  The subject of this discussion, the 1820 Square 2, Large Date, No Knob, is pretty self-explanatory: the base of the 2 is flat (or squared) instead of curving, the date is Large (requires comparison to determine the correct size), and the top of the 2 ends in a point instead of a knob.  In terms of surviving examples, this major variety appears to be the second rarest of the five, though it should be pointed out that the populations of all five are fairly close.  Mint State examples of all five varieties are scarce to rare, and the 1820 Square 2, Large Date, No Knob is no exception.  As of the April 2012 PCGS Population Report, PCGS had certified only 18 Mint State examples, the finest of which is a single PCGS MS66.
