The weird thing to me is that the total mass of silver mined is only about 8x the total mass of silver, but the price spread is 80x.

Copper is much more abundant, over 400x more copper than silver has been mined, but silver is almost as scarce as gold. It really seems like the price spread should be closer.

For anyone that is curious, it's about 4.5 double chests of gold block stacks in minecraft. Not particularly difficult, but a challenge nonetheless.
