Police are appealing for witnesses after three raiders broke into Bashall Barn last weekend.
In the early hours of Saturday, three men targeted the locked and secure business in Twitter Lane and gained entry via a side door. Once inside, they damaged the lock and disabled the alarm.
The offenders made an untidy search of the premises before escaping with loose change.
CCTV footage is currently being examined by police.
Anyone who witnessed anything suspicious should call police on 101.
