1976 S U.S. Trade Dollar with 1 Chop Mark on reverse

1876 large S (San Francisco) U.S. Trade Dollar originally graded by PCI in Tennessee (no longer in PCI holder) as an AU-58. This is a beautiful Trade Dollar with one chop mark on the reverse on the right leg of the eagle.
Originally made for trade with China many of these coins were "chopped" and gouged while in circulation to verify they were genuine. I have many examples with multiple chops and digs, and this is the least damage of the group.
All details on the coin are sharp and well defined and there is almost no wear on the coin. Except for the one chop mark this coin might easily be gradable as a MS-60 or better?
I will start it at 99.00.
