Olivia Newton-John and Electric Light Orchestra (ELO) – ‘ Xanadu’ (1980)
The movie may have not been popular, but the record featuring the theme song is still sought-after. Olivia apparently hated how she looked on the cover so she stopped the pressing. Only about 25 records survived and they’re now worth $9,100.
Hank Mobley – ‘Blue Note’ (1957)
Around 1000 copies were printed of this record but because Blue Note ran out of labels during printing some copies are worth more than others. The copies with the standard address sold for $11,162, while the other copies are worth even more.
