The way I've always envisioned it, and this has been very well accepted by everyone:
Corperate issued script. A virtual confetti of corperate logos and bills of all varying denominations. Corperations would issue their empoyees their own script, but in a store or basically anywhere on red you'll find a sampling of just about every corperation in Withmore. It's all just paper, and worth less than the paper it's printed on. Just like an american dollar. The only thing that gives it any value is the agreement by all businesses to use it as their common form of currency, and to accept it as a promisary note for all debts, private and public. Just like an american dollar.
I frequently emote my money in conjunction with paying people.
pay 100 to rycheck
emote slaps a crisp bill with the ZMI logo on the bar, and slides it across to Rycheck with one finger, "Keep the change".

I mean, it's kinda hard for someone to trade on a multi-national level with currency that's only recognised in one city.
Is it based on a gold standard? and if so, does that mean there's a stash of gold somewhere that I can steal? :)
*is a dork for doing conversions to actually see what something would be worth IRL, but, who knows?*
Anyways:
1 dollar = 20 chyen
5 dollars = 100 chyen
10 dollars = 200 chyen
20 dollars = 400 chyen
100 dollars = 2000 chyen
Or, we could go with a system I noticed in the Ghost In The Shell series, where paper currency is an archaic, but still used system where the currency value of the fiat is printed directly onto the bills, along with serial numbers and digital signatures for every piece of fiat produced, linked to credit from a particular banking or financial institution. Essentially, any denomination could exist.
Oh, and to point something out, Kevlar's vision of the banking system is very reminiscent of the pre-Maoist, pre-WWII invasion banking days of China, where every lending institution had its own currency. This idea even goes back further, and has had a place in almost every developing nation's economy, including that of the US.
Just a wads, coins, cred, and hard script in the bank,
