Assumptions and limitations

  • Coin constants describe current standard US coin specifications: 2.5 g cent, 5 g nickel, 2.268 g dime, 5.67 g quarter, 11.34 g half-dollar and 8.1 g dollar coin. Historic coins can differ.
  • Each note is approximated as one gram. Packaging, wear and dirt are excluded. Fractional amounts imply fractional pieces in the arithmetic; choose amounts divisible by the denomination for a realizable all-one-denomination stack.
