Where by Royal Edict, the 8-Escudo was to be minted at the weight of 27.1168 g. @ .875 (23.7272 Fine Au), a pristine 8-Escudo should weigh at least ~27.115 g, 418.475 English Grains Troy.
Citation: Universal Cambist and Commercial Instructor, being a general Treatise on Exchange, &c. Vol. 1, (1811) pp. 390-1
Cited in Kelley (1810), by English Mint Assay the "new" Spanish Doubloon/ 4 Pistole weighed (417 Grains/0.86875 Ozt; 27.02115 g.) but .864 Fine Au. However, this average coin weight was for circulated 1801 8-Escudos up to 1809, ~8 years.
On average, a full-weight 1801 8-Escudo lost 0.1845 Grain Troy for each year of circulation.
Presumed to be 366.1666667 Grains Fine Au (0.762847223 Ozt),
