Discussions on Finance

I *think* it might be best to have largest denomination issued placed within currency, with maybe a reverse property linkage to the issuing country (or organization if it's not a political entity but a mercantile or other institution).

 Another idea is to capture the historical (ie. dated) introductory, high and lowpoint of exchange rate against some benchmark currency (usually the US Dollar for most of the 20th century to current date). Sort of like the Exchange Rate type of the finance base. Another thought is to have what the debased currency replaced and what replaced it, Yugoslavia in the 20th century would be a great testcase for this as we had multiple entities that was known as Yugoslavia and Multiple currencies up to the final breakup into many countries.

The only outliers to including largest denominations within currency are bank notes, such as French assignats, denominated in livres or francs. Still, this is the less frequent case and denomination under currency seems more logical.

The exchange rate benchmark could be difficult to establish over time. Early colonial Americans paid in tobacco, but once tobacco became plentiful it declined in value. Similarly, Spanish and Californian gold discoveries decreased the relative value of that historic base. Thanks to Bretton Woods, the US dollar has been the global benchmark for half a century, but time will tell how long that lasts. Replacement currency+denomination would be deterministic in cases the country remained relatively intact. In the case of the Roman Empire, though the denarius was used for centuries after the fall, it would be more challenging to identify successor currencies?
