Large Denomination Notes in Modern Commerce
Despite being the largest bill in everyday use, $100 notes are less common in point-of-sale transactions than smaller denominations. High-value purchases and automated clearing still rely on electronic transfers, reducing the need for physical cash among businesses and consumers.
Large denomination notes remain useful for certain cash-intensive transactions and for collectors who value uncirculated or series-specific designs. Their role in the modern economy is specialized but still recognized by law and financial institutions.

Today, the $100 note is the highest denomination produced in regular series. Historical high-value bills are collectors' items, but the $100 series 2009 FRN remains the functional standard for paper currency at the top end of everyday cash use.
