Currency Examples
The following are real-world examples and brainstorming for marking up currency.
The Problem
Currency is a reasonably easy problem to solve as indicated by the #Existing_Practices.
"Amounts" in arbitrary units is a bit harder and necessary for several applications.
For example, consider the work that has been done on a recipe microformat.
Though we haven't reached this problem yet in the research, I can see it coming:
Say you wanted to create a "shopping list" application which you could tell which recipes you wanted to cook, and have it automatically total up all the various amounts of ingredients and give you the net amount of stuff you wanted to pick up.
It would need to be able to determine precise amounts/units of each ingredient. This might turn out to be like the currency problem, or it might be more complex, given the variety of units used in recipes, English vs. metric etc. That's a case that might need a microformat. We need more research and analysis to really justify it, but I can see it within the realm of probable possibility.

Brainstorming
Charles Iliya Krempeaux
Maybe something like...
Pay me <abbr class="currency" title="CAD">$</abbr>5.00 now!
Although something like the the following might be better...
Pay me <span class="money"><abbr class="currency" title="CAD">$</abbr>5.00</span> now!
But it might be more semantic salt than is considered necessary. Just having the abbr with the class-currency near a number might be good enough. But that's open for discussion though.
Ben Ward
Could pure HTML be sufficient?
<html lang="en-gb"> <p>My new T-Shirts cost £30, but it cost my friend in Canada <span lang="en-ca">$34</span></p> </html>
Arve Bersvendsen
<p lang="nb">Den kanadiske prisen på t-skjorten var <span class="currency CAD">34 $</span>.</p>
Mike Stickel
<span class="money"><abbr class="currency" title="CAD eng">$</abbr><span class="amount">5.00</span></span>
In this format the wrapping would be "money" or something similar followed by either the actual "amount" or the "currency", depending on what rules your country/language follows in regards to the order. Since there can be a difference between different languages within countries I thought it might be a good idea to include that in the "currency" definition of the formating, eg., "CAD eng" or "CAD fr". It could also give sites that list multiple languages a way to differentiate when they show multiple prices.
Ciaran McNulty
The only microformat that I've noticed currency units in is hListing, and that deliberately shies away from parsing the actual values because it's too free-form in most existing Listing formats.
My own preference would be for something like:
<p class="money">This item costs <span class="currency">GBP</span> <span class="amount">10.00</span> </p>
Which with similar parsing rules to existing formats would also allow things like:
<p class="money"> It'll cost you <abbr class="currency" title="50.00">fifty</abbr> <abbr class="amount" title="GBP">quid</abbr> , mate! </p>
Or, a more complex example with multiple languages:
<p lang="en">Price: <span class="money"> <abbr class="currency" title="GBP">£</abbr> <span class="amount">1,250.00</span> </span> <span lang="fr" class="money"> (Prix: <span class="amount">1600,00</span> <abbr class="currency" title="EUR">€</abbr> ) </span> </p>
