This figure has been reported (for example in The Guardian) as ten dollars. cinemablend.com agrees, but may have gleaned this from the Grauniad (whose article it cites).
According to the Academy's own regulations however, the figure of one dollar is correct.
The Grauniad's article is about the Oscar won by Joseph Wright in 1943 for colour art direction on the film My Gal Sal. "Wright's nephew Joseph Tutalo", says the article, "had sold the statuette at auction, in contravention of a 1951 Academy bylaw that requires winners to offer any Oscars back to the organisation for $10 before attempting to sell them on the open market."
An Australian news site reports that "the Academy is also attempting to buy back [Wright's Oscar] for just $10", and that in 1975, "a jury ruled that if [Mary] Pickford's heirs want to sell her statuette, they first had to offer it to Academy officials for $10 instead of auctioning it off for as much as $800,000." This, I suspect, is the source of the confusion. The Academy probably feels it's being extremely generous to offer $10 for something it believes should be its by right for the price of only $1.
