US HB4459

Eliminates production of the one-cent coin (penny) for general circulation, while allowing continued production for sale as numismatic collector items

Authorizes an alternative composition for the 5-cent coin (nickel) using a zinc inner layer with a nickel outer layer, with weight between 4 and 6 grams

Grants the Secretary of the Treasury authority to prescribe the specific zinc-nickel composition for nickels, contingent on testing that demonstrates reduced production costs
