Watch List notes:

GREAT BRITAIN. Great Britain - Spain. Dollar, ND (1797-99). George III. NGC EF Details--Reverse Rim Damage; Countermark: AU Strong.
S-3765A; KM-626. Bank of England type I countermark; bust of George III within oval indent on a Spain 1792-S C bust 8 Reales of Charles IIII (IV). The host is well struck and gently toned, with almost no noticeable marks except for the rim nicks on the reverse. The countermark is crisp and detailed. Overall a very presentable example of this famous type.

The oval and octagonal Bank of England countermarks in this sale represent a small sampling of a much larger issuance showing clear evidence of being struck on multiple surfaces and using a variety of legitimate and ill-legitimate punches. The high grade examples of both countermark types each bare characteristics that can be identified, but are unable to be attributed to a specific location other than just the "Bank of England". It makes sense that these were probably countermarked in multiple branches of the Bank as both punch types originated from the government; the oval type being an official Hallmark while the octagonal type utilized the bust of the then current 6 Pence.

Estimate: $400 - $600
