[Ninurta]

@"Ninurta" 

Its symbol was d, from the Roman denarius.

... sez Wikipedia.

But that is odd, because Wiki goes on to say the denarius equaled 10 asses 

The word dēnārius is derived from the Latin dēnī "containing ten", as its value was originally of 10 assēs

so that still leaves the question as to why a coin associated with 10 of something came to be the source of an abbreviation for a coin associated with 12.

Cheers

Thanks for that! Now I know, and it has bothered me ever since I went over the ledgers of the Dunmore's War expedition (5 ledgers in all, now stored in the Library of Virginia) and tried to puzzle out the pay rates and prices of commodities out of them!

At that time, Daniel Boone is listed as having sold buffalo hides to the militia at Fort Russell in Castle's Woods, VA (now "Castlewood" in Russell County, VA), and some of the militiamen bought their muskets after their service for personal use on the frontier at 10 to 18 shillings a musket, roughly 10 days wages for the average militiaman back then.
