1620-1920 Pilgrim Tercentenary Silver Commemorative Half Dollar.  This was struck in 1920 to commemorative the 300th anniversary of the Mayflower landing in Plymouth, Massachusetts.  The obverse features a Pilgrim, while the reverse shows the Mayflower.  Although 152,112 were minted, many were returned to the mint to be melted, so much less are available today!  The is of the exact coin you'll receive.  It does appear to have seen some circulation and exhibits nice pleasing gray surfaces.
