When reading this ADR, I was confused about _denomination_. When reading this in context of tokens I always think about a unit / measure. Examples: bills denominated in $20 and $50. Or as 100 cents makes 1 dollar.
The Merriam-Webster dictionary defines [denomination](https://www.merriam-webster.com/dictionary/denomination) as:
1. an act of denominating. Eg: the denomination of prices in U.S. dollars
2. a value or size of a series of values or sizes. Eg: metric denominations
3. name, designation especially : a general name for a category
It seams that we are using the last definition (3rd).
