Watch List notes:

Santiago, Chile, gold bust 4 escudos, Ferdinand VII (bust of Charles IV), 1815FJ, unique (unlisted), NGC XF 45, finest and only example in NGC census. KM-unl (77 for type); Cal-unl (Type 413).Slightly off-center strike on a broad flan, with obverse center weak (some wear, too) and with minor laminations, light toning around details, clear date (despite break at bottom of 5) that has not come to light publicly till now (probably less than 100 were struck), hence a major discovery piece for Chilean collectors.
