The same act also resolved the difficulty in minting the "standard silver" of 89.24% fineness by revising the dollar's alloy to 412.5 grains, 90% silver, still containing 371.25 grains fine silver.

The current relevance of these units: The Spanish peso or dollar was historically divided into eight reales (colloquially, bits ) – hence pieces of eight . Americans also learned counting in non-decimal bits of 12 + 1 ⁄ 2 cents before 1857 when Mexican bits were more frequently encountered than American cents; in fact this practice survived in New York Stock Exchange quotations until 2001. In 1854, Secretary of

However, by December 1861, the Union government's supply of specie was outstripped by demand for redemption and they were forced to suspend redemption temporarily. In February 1862 Congress passed the Legal Tender Act of 1862 , issuing United States Notes , which were not redeemable on demand and bore no interest, but were legal tender , meaning that creditors had to accept them at face value for any payment except for public debts and import tariffs.

The p and the s eventually came to be written over each other giving rise to $ . Another popular explanation

4312-576: The origin of the word "sterling". The Oxford English Dictionary states that the "most plausible" etymology is a derivation from the Old English steorra for "star" with the added diminutive suffix -ling , to yield "little star". The reference is to the silver penny used in Norman England in the twelfth century, which bore a small star. Another theory holds that the Hanseatic League
