A couple has been sprung allegedly printing fake $50 notes in their Gold Coast home.

Police allegedly found the 27-year-old man and 19-year-old woman making counterfeit notes on Tuesday, following a tip-off from a member of the public.

The fake notes all have the same serial number, are a slightly different colour from normal notes and don't have a transparent hologram in the plastic window.

Detectives allegedly found $600 in bogus $50 notes at the property.

It is alleged the pair had been using the fake notes to buy small items from convenience stores and pocketing the change.
