The bronze figure modelled on Euterpe, muse of music and lyric poetry, was presented to the Fab Four in 1966 for excellence in songwriting and composing.
An unnamed woman took the statuette home in the 1980s after finding it in a derelict office block in London, and she used it to prop open a door in her home.
The award will go on sale on Tuesday at Dreweatts auction house in Bristol, England, and is expected to fetch more than £3,000.
A spokesperson for Dreweatts said: "It's an amazing find."
