👉 In finance, a subdenomination is a denomination that is smaller in size than its parent denomination. For example, a 100 cent (penny) is considered to be a subdenomination of a 25 cent (nickel) coin. Subdenominations are often used when dealing with denominations that have different values or are not easily divisible into single units, such as bills or coins. They can help simplify the process of converting between different denominations and make transactions
