Currency in Aman and Arda?

And in Bree and the Shire, where there was apparently no central government or authority, and thus no "government" workers, only currency trading or bartering would make the local economy workable. I'm inclined to think it was only currency, because of something Butturbur said.

Additionally, I don't recall any reference to banks or counting houses in Bree or the Shire where currency exchanges could be done, and the Kingdom or Arnor had been gone for over a thousand years, so I would think the coins would have been simple metal discs, accepted everywhere the inhabitants of those areas were likely to go.

The currency systems of the Shire and Gondor were discussed last year in this thread (which also contains some links to older ones). It seems plausible to assume that the Hobbits inherited their monetary system from the North Kingdom of old, and that the currencies of Gondor and Arnor were more or less alike if not the same (possibly pre-dating the kingdoms in exile and originating with the Númenórean colonial empire, like Legate suggested).

Probably yes. I also can't quite see the Dwarves returning home from their travels with caravans of cattle and wagons laden with grain - it seems more likely to me that they sold the products of their craft for coin which they used to buy food from Men who lived nearer their homes and have it delivered to them.

In general, I think the Dwarves were somewhat more preoccupied with notions of property and private ownership than the Elves - at least in their dealings with other peoples (see the quarrel about the Nauglamír back in the First Age). Among themselves, such issues may not have mattered quite as much, except perhaps between the different Houses (e.g. I could see the Longbeards of Moria trading mithril for gold and silver with their distant relatives); but I doubt they used any internal currency for that, in so far I'm with Legate here.

As for the Elves, I feel Legate has hit the nail on the head; and when we're talking about Aman, any idea of trade and barter seems quite out of question to me. (If you want evidence, the Silmarillion says the Noldor freely gave gems and jewels to the Teleri to do with as they pleased; and later, Fëanor in turn didn't ask Olwë 'How much for those ships', nor did he demand them as recompense for earlier gifts, but asked for permission to use them for old friendship's sake.)
