English term that groups notes and coins of a currency

Question

I'm programming a web application and I need to name the "class of things" that are notes and coins.

So far the best I could find was "currency piece".

Is that the correct way of naming the notes and coins of a currency? Are there any alternatives?

Answer 1

I would go with cash, which is defined by NOAD as “money in coins or notes, as distinct from checks, money orders, or credit: the staff were paid in cash | a discount for cash”
