(2.121 cm diameter / 2)^2 * pi * 0.195 cm height = 0.689 ml
5 US gallons = 18 927.0589 ml
18927.0589 / 0.689 = 27 470 would be the upper limit. They would not pack ideally like that so the real number would be less.
Assuming a nickel would take up as much space as a hypothetical box with sides the same dimensions as the nickel 2.121^2 * 0.195 = 0.877 ml.
18 927.0589 / .877 = 21 581.5951 = 21600 nickels might be the lower limit. They might pack better than that.
