Late Spanish Pillar-Dollars

c.1809 The piastre and Dollar had significantly higher and likely more consistent value to British merchant in the Americas.

March 1810:

Testimony the US Dollar actually weighed 0.8625 Ozt, 0.780697589 Ozt Fine Ag.
At full Mint Weight, 1,000 US Dollars weighed 864.58 Ozt; average circulated Dollars weighed 862.5 Ozt, or the loss of 1.886 Ozt Fine Silver per 1,000.

Average Circulating Dollars would have become underweight in 7.5 yrs, but (by late 1809) no new Dollars had been minted in over 5 years. The 'Average Dollar' would have been minted sometime around August 1798.
