Watch List notes:

Great Britain, 1 dollar, George III oval countermark (1797-99) on bust of Potosi, Bolivia, bust 8 reales, Charles III, 1776 PR, NGC XF details / obverse damage, cleaned; c/s AU strong. Sp-3765A; KM-624. Ironic combination of a British countermark on a Spanish colonial coin dated 1776, the year of American independence and the beginning of Spanish undercover aid to the American revolutionaries, an issue famously nicknamed at the time "the head of a fool on the neck of an ass," this example with very bold and deeply impressed countermark, lightly worn host with pockmark in field in front of neck, a bit shiny but starting to retone in legends.
($350-500)
