1017: £ Sep 21, 2017

The symbols for the currencies euro, €, ruble, ₱, won, ₩, and the yen and yuan, ¥, and many others including the no longer used Dutch florin, ƒ, are all at least partially based upon the first letter for the name of the currency, though the euro is also said to be from the Greek lunate epsilon, ϵ, as Greece is said to be the cradle of European civilization. Still, the dollar-sign, $ and the pound-sign, £—though the symbols are not arbitrary—do not appear as obvious necessarily. The £ comes from the first letter of the name for the currency as many others do, but in this case the name is from Latin, not the native language. The Latin word for 'pound', as in a weight or balance, was 'libra', related to other words from Romance languages like the French 'livre' of the same meaning, as well as the source of the abbreviation 'lb.' for pounds when referring to weight.
