1795


USA:





1810: Kelley's Universal Cambist records assays and weights for various circulated Dollars. Where the English Standard was .925 (37/40th Fine, or 222 per 240 dwts per English Troy Pound), c. 1809 assay of the 1795 Silver Dollar was rated 0.897916667 Fine Ag, 0.62% Better than US Legal Standard.

Citation: The Universal Cambist and Commercial Instructor, Being a Full and Accurate &c.  Patrick Kelly (1811)


In 1792, the fineness of US Coin Silver was set by law at 0.892427885 Fine Ag.


 



Late 19th, 20th C.: the fineness of US Coin Silver has been assumed 0.892 Fine Ag.


1795: $1. = 0.867958333 Ozt



A Dollar (1795 - 1804) must weigh at least 0.864583335 Ozt



Erroneous assumption: fineness of USD Coin was not 0.89583 Ozt
