Cents on the Dollar

How much of a dollar bill can you cover up using change for a dollar? The coins must not overlap one another.

A not-very-good effort is pictured below. The four quarters only cover about 18% of the dollar bill's area.

Send me a picture of your best effort!

N.B., I made a spreadsheet that you can use to score your attempts. Edit the blue values in the spreadsheet to reflect how many coins of each type you used. Please don't edit the formulas, or others won't be able to use the spreadsheet. (Let me know if there are errors.)
