Silver coins are slightly smaller than dimes 09/05/2016 06:58 PM CDT

There are 160 silver coins to a pound, or 0.1 oz/coin. 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 πr^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/(0.135π)) = 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 :)

They really should have modeled them on the three cent silver piece. We could hold nearly 4 times more coins before becoming encumbered.

Halflings of Elanthia would rejoice!

Ah, but silver coins are accepted everywhere and for the same value, so they're clearly valued intrinsically, not fiat currency.

Thus, if you had a silver coin with a quarter of the weight, it would only have a quarter of the value. Halflings are in trouble either way.

LOL, touche.

Fine, gold coins and other stuff like in DR! Actually it's probably a much more cumbersome system than it makes up for, but at least on paper it sounds good.

Veil iron currency, here we come!

Platinum and gold coins in DR also made pickpocketing something to actually worry about. I'm not sure if that's really the case in GS anymore?

All of this theory is based on the assumption gravity is equal.

In as much as determining the size of the coin, that's true. However, as far as the encumbrance effects, we are weighing them, which implicitly includes gravitational effects.

The mass of two coins might be different, but if they weigh the same they weigh the same.

...which to follow up...

considering humans in game weigh something similar to humans in real life, then we can basically know the gravity is roughly the same, too.

So there :P

Unless, of course, humans use the lesser mass value, and the giantman pound is based off of a larger mass value (always enjoy the 'which weighs more, a ton of. . . ' challenges). Elves - Avoirdupois, Humans - Tower, Goblins - Lower, Giantman - London. Whee!!
