All currency values in USD.
vs.
All currencies values in USD.

Q1:
I always notice “All currencies values in USD” is written on receipts.
Why is it not currency but currencies? Isn’t “All” here means “every”? Hence, every currency.

Q2:
By the way, do I need the word “is” in my question?

Thanks a bunch.

Hi,

I would choose ‘All currency values ARE in USD’. ‘Is written’ is all right because it refers to what is written.
