Let's stay I have a table like that

0 - 100$
100$ - 200$
200$ - 300$
300$ - 400$

I want to say that the prices are grouped by ???? of amount.
If I translate from French, I find the word "slice" but in my opinion it is only for bread and cannot be used for amounts...

Have you got any idea of what word I should use?
Thxs in advance!
the prices are grouped in denominations of 100.

the word you are looking for is denominations.
Thanks Amanda!
