Luxist provides 3 ways you can get rid of your little gold man:
Resale value for Oscars won after 1950 are limited because the Academy makes all winning celebrities sign an agreement that if they want to sell they have to first offer the statue back to them for R7.50.
Based on the current price of the gold, if melted down each Oscar is worth about R3700.
If sold on the sly (or for pre-1950 Oscars that can be sold in the open) big-name Oscars will easily clear R500000.
