Two rare early editions of Mein Kampf, signed by Adolf Hitler could sell for more than $US20,000 ($A22,373) at an online auction, officials say.
Nate Sanders, owner of Nate D Sanders Auctions in Los Angeles, says he knows he'll catch a lot of flack for putting rare 1925 and 1926 editions of the racist screed up for bid.
"But it is a piece of history. It is a very rare item," he explained.
Hitler was arrested and jailed for the attempt to seize power. He dictated Mein Kampf, two volumes of autobiography and anti-Semitic manifesto, to Rudolf Hess while behind bars to raise money for his criminal defence.
Both volumes' fly-leaves feature Hitler's signature.
Sanders said volumes of Mein Kampf from the 1930s are common, but a copy signed by the author is rare.
Sanders is also auctioning off a leather trench coat he said was worn by Albert Speer, a Nazi government minister who was sentenced to 20 years in prison for his role in the Nazi regime.
Selling Nazi memorabilia is prohibited in many European countries that saw the horrors of World War II.
