Belson Bucks is Belson's own custom form of a dollar that appears in "Clarence's Millions". They are better made than Clarence Dollars. They might've been made by a graphic design company, not hand made.
They are crimson slips of paper with Belson's name on the bottom, a $100 on the bottom left and top right corners, and Belson's face in the middle. Belson in the photo has a top hat, a monocle, and a bowtie.
