I had no idea it was the famous collector King Farouk.
This is a part of an article talking about King Farouk collection, for the full article the link is;

The issuers of the export licence required for virtually all gold coins, in force under the extensive gold restrictions in effect since March 1933, did not recognise the significance of an unissued 1933 coin, and the Treasury Department inadvertently issued the export licence.
In 1954 the Double Eagle was put up for sale with other valuables in King Farouk's private collection. Sotheby's, acting on behalf of the new Republic of Egypt, was in charge of selling the astonishing collection assembled by the dethroned monarch, who was one of the most enthusiastic coin collectors of all time. The sale of his collection of more than 8,500 gold coins took nine days. During the auction the US Treasury Department requested that the Double Eagle be withdrawn from sale. This was done, but afterwards it disappeared under mysterious circumstances and nothing was heard of it for nearly half a century.
In 1996 Secret Service agents posing as buyers set up a sting at the Waldorf-Astoria Hotel in New York and managed to seize the coin from two dealers, one of them British, who had apparently been attempting to sell it. A five-year legal battle ensued, as a result of which a singular settlement was made between the American government and the British dealer under which the coin was officially released to the latter's private ownership. Thus was based on the understanding that it was previously owned by King Farouk and officially recognised as US coinage.
Now that Egypt has been unable to retrieve the coin its new, unnamed owner will be given an official Certificate of Transfer which makes it legally his. The substantial sale price will be divided equally between the British dealer and the US Treasury's General Fund. "
