Size of Silver Coins
Silver coins are slightly smaller than dimes. PFLATS from the Officials calculated it – now that’s what I call making the most of your math!

There are about 28.3 grams per ounce, so each coin weighs about 2.83 grams. Silver is 10.49 g/cm^3. That gives us 2.83/10.49 = 0.2698 cm^3 of silver.The volume of a cylinder is ?r^2h. If we use the thickness of a dime, 1.35 mm = 0.135 cm, we can solve for the radius: r = sqrt(0.2698/(0.135?)) = 0.79758 cm, for a diameter of 1.595 cm.
So a silver coin, if it were the thickness of a dime (1.35 mm) would have a diameter of 15.95 mm. A dime has a diameter of 17.91 mm.
Volume-wise, a silver coin is 79% of the volume of a dime. At the same thickness, a silver coin is 89% of the width/diameter of a dime.
that would be a fun use of the math extension on the Wiki 🙂
Halflings of Elanthia would rejoice!
