The US is set to make its final penny.

The Philadelphia Mint will strike its last batch of one-cent coins on Thursday, after more than 230 years of production.

The coins will remain in circulation but the phase-out has already prompted businesses to start adjusting prices, as they say pennies are becoming harder to find.

The government says the move will save money, or as President Donald Trump put it in February when he first announced the plans: "Rip the waste out of our great nation's budget, even if it's a penny at a time".

Pennies, which honour Civil War president Abraham Lincoln and are made of copper-plated zinc, today cost nearly four cents each to make — more than twice the cost of a decade ago, according to the Treasury Department. It estimates the decision to end production will save about $56m a year.
