Make the Half-Dollar in such a quantity that it becomes a common currency like the Quarter, Dime, Nickel, & Penny

Due to rising inflation, we see that many coins are becoming a hassle to carry. That said, rather than eliminate other coins, why not increase the quantity of Kennedy half-dollar coins to a point where they are not solely for collectors, but become a viable resource for payment? Two quarters does the job, but the Half-Dollar is one of America's most historic specie amounts and only in recent years has it been virtually abandoned. Cash registers that are currently in use have a spare slot that could easily be retrofitted for the Half-Dollar, and it will still be a collector's item for those who wish to have one of every currency. Please address this for those who wish to see more Half-Dollars minted.
