Coin Shortage ?
My Credit Union lets us just dump coins in their machine for free.
About once a year I take all my spare change including lots that were found in FL washers traps, some of it is really dark and discolored, Last time the Lady working at the CU said I should keep my coins in a dry location when she saw how discolored some were, LOL
I have long thought that the US Government should encourage people to return change , maybe by requiring banks etc to have free sorting machines.
It is both wasteful and unpatriotic to hard coins, you are costing the USG money [ your money too ] because they have to make many times the number of coins actually needed.
It is also environmentally unsound to hoard coins, doing so wastes energy making something that the world does not need, the amount of mining world wide to get the metal and the Hugh amount of energy consumed making and disturbing new coins much of which could be eliminated, use of Coin and even paper money is going way down, it really might not even necessary to ever make any more metal coins.
