Constitutionally, money is gold and silver. The reason the fed went off of the gold standard in 1933 was because they were printing up more gold "certificates" than they could actually redeem with gold.

You can't print gold, that's why the fed likes paper instead -- paper currency can be inflated.

All those who don't know that The Bernak is a thief, a stooge and a clown, please raise your hands.
