Watch List notes:

Great Britain, 1 dollar, rectangular George III countermark (1797-99) on a Mexico bust 8 reales, Charles IV, 1797FM, encapsulated PCGS XF45. Sp-3766; KM-656. Much scarcer than the oval variety and bordering on rare at this level (only five coins XF45 or higher at PCGS for all hosts), with rich rainbow toning and traces of luster on well-struck host and virtually uncirculated countermark showing the sharply struck bust of George III. We note that an NGC AU 53 example of perhaps lesser quality hammered for $2600 in Heritage's April 2017 auction.
