As taxpayers, we do not win. It costs money to mint the coins, then a substantial amount for the CC fees, then substantial costs for the packaging and USP overnight delivery. The bank does not win because of the cost to count the coins and send the coins back to a fed vault (if it was not costing the banks money, why would they put up a fuss about receiving them?). And yes the banks do get charged extra by "Brinks" for all the extra bags of coins.

Others have said that the mint is still making a profit. However, the profit that they are making, if in fact they are making a profit, are reduced by the costs associated with the minting and delivery of coins that just wind up back in the Government's vaults.

There is no way for everyone involved in the chain of coins to "win".
