This probably needs legislation to make work.
Stop printing the ones until the stock plie of dollar coins that the Federela REserve is storiing goes down, to the point the quantity is "normal" inventory. Then restart printing of the dollar bill if you must. Just stopping the presidential dolla coin program is not going to do anything for the coins in storage right now.
And I have often asked for dollar coins or half dollars a the bank and they say they dont have any. They can't circualte if you can;t get them.
