Hi,

Thank you for your reply. What you say about assuming the coin is a cylinder is correct, and gives an approximate answer as to the volume, but it is not accurate enough to determine the volume for density measurements. Coins in general have depressions that are not taken into account when the thickness is measured.

Putting the coins in a measuring cylinder would certainly work for many coins. Is there a method that would give enough accuracy to determine the volume of one coin to get the density to one decimal?

Thanks,

Wayne
