So, have some paper dollars stored under the mattress.
Better to have dollar coins, imo.
A box of 1000 weighs ~18 pounds.
Somebody might grab your 10000 paper dollars no problem, but 180 pounds of coins will require a dolly.
Not to mention that coins are treasury money, not fiat paper dollars.
They are the money of the united snakes, where paper dollars are a contracted iou.
