Brimming With Beer, in Brimington, price all their stock to the nearest 5p- but offer certain percentage discounts which throw up prices that involve 'coppers'.
Landlord Ben Stephenson said: "The time spent counting up copper doesn’t warrant doing basically, and after a recent trip to Czech Republic, where they round to the nearest Koruna, the decision was made to run a trial.
"A lot of customers will ask for their change to be put in the charity box if it’s not a significant amount.
"More than half of our customers pay by card so won’t be affected by the change. The most a customer would loose or gain is 2p."
The trial is set to run until September 30 and, if successful, Brimming with Beer will become 'copper free' permanently.
"We've already had a positive response, with customers saying it's a great idea," added Ben.
