I have no ready money
 

Situation:

I usually pay for goods by credit card, so I just have $1000/500 notes, which are large denomination notes in my area and not commonly used in daily retail transactions, but not coins and $10/20/50/100 notes. I think saying

-I don't have coins and $10/20/50/100 notes.

is too cumbersome; can I convey the meaning by this?:

-I have no ready money.

In Chile we would say "No tengo sencillo" meaning lower denomination bills and/or coins. I don't think it is like that in other Hispanics countries.

No, 'ready money' is used to mean that you have the amount needed, and you do, indeed. The real question is can the merchant accept a large denomination note. (Can they make change?)

You could say, "The smallest note I have is ____. Will you accept that?"

Thank you, Rusty~

How about if a man asks me 'Could you give me change for a $500 note?'? Is it natural English to say?:

-Sorry, I don't usually keep coins and small denomination notes.

The most common way to say I have no ready money in English is to say
I have no cash.
Ready money usually means a very large amount in the bank as opposed to money invested in things.

Can you change a $100 bill? or Do you have change for a $100 bill?
This is American English. British English used notes instead of bills

Do you need the term in Spanish? Chileno provided you with one term. There are others.

How can we say ready money in Spanish.?
