Watch List notes:

Tortola, 4 shillings 1-1/2 pence, countermark TORTOLA inside contoured rectangular indent (Type I, 1801) on a 1/2 cut of a Potosi, Bolivia, bust 8 reales, Charles III, 1778 PR, rare, NGC VG 10, C/S VF standard. Prid-1; KM-7. 13.04 grams. A very handsome survivor from Tortola's first issue, made from countermarking a bust 8 reales (in this case from Potosi, with full mintmark-denomination-assayer visible on reverse and 78 of 1778 date on obverse) with TORTOLA in neat letters within a box reading vertically upward to right of center where the host coin was cut in half vertically (typically curved), all richly toned and the countermarked deeply recessed, a rare and desirable issue no matter the grade but even rarer as undamaged and numerically gradable, in fact tied with four others for second finest in NGC census behind a single Fine.
