The current half dollar is a rejected monster. Nickels should be too.

Shifting a decimal place works for me. Prices when I grew up up in the 60s & 70s were a fraction of today's. Penny candy WAS REAL! And the "five & dime" had stuff for, well, nickels & dimes. Not a lot, but some things. Nowadays it's dollar stores (a blight on the landscape) - their prevalence tells ya sumthin'bout the disposable income situation of many, many citizens.

Yes, and reduce the size of new_half_dollar to current_quarter; new_quarter to current_nickel; dime remains same size. Nix nickels and pennies. Dollars become smaller than current_half_dollar, but larger than current_quarter.
