It would be easy if we lost the coins that are essentially without value - pennies for sure, and probably nickels as well. What do either of them buy you today? Canada had the right idea there.
Dimes and above can be debased easily enough if necessary, although they already cost less to produce than what they're worth and should remain that way for some time.
as a digger, I would never support removing coins from circulation.
Even Pennies.
First off other countries have done this &
those coins are now as valuable as the rocks in the ground with them.
If we get rid of the Penny, eventually the fed will get tired of taking them back.
the most banks already complain on dirty damaged coins.
so once they are off the Grid, they will eventually become useless.
and unless the price of copper Skyrockets,
all those pennies from the 1940's up that survived the rot,
may as well have rotted away

as rottin' tin bean cans will have the same value.
Imagine finding a Cache of 100,000 preserved Zinclons in a large Plastic Water Jug,
and the Plastic water jug has more Value as a bank to hold Dimes & quarters
and there is a Bill in congress to get rid of dimes & quarters because people don't use anything
less then paper $10.00 Dollar bills any more
same goes for nickels.
give them an inch to take something from us, they will use the Precedent
as a hint that they can take much more
