Sept 17 (Reuters) - An extremely rare official first-edition printed copy of the U.S. Constitution, as adopted by America's founding fathers at a convention in Philadelphia in 1787, will be put up for bid by Sotheby's in mid-November, the auction house announced on Friday.

Sotheby's, announcing the upcoming sale of the document on the 234th anniversary of its signing by delegates to the Constitutional Convention, estimated its value at $15 million to $20 million.

It last sold for $165,000 in 1988, when it was acquired by the late S. Howard Goldman, a New York real estate developer and private collector of American autographs, historical documents and manuscripts.

His wife, Dorothy Tapper Goldman, is offering it for sale, with all proceeds going to the charitable foundation established in her name to further the public's understanding of democracy, the auction house said.

The document is one of just 11 known existing copies - the only one still in private hands - from the official first printing of the final text of the Constitution, as adopted in Philadelphia and submitted to the Continental Congress for review, Sotheby's said.

Copies from that first printing, bearing no signatures and believed to have originally numbered about 500, were also furnished to delegates of the Constitutional Convention itself. Two surviving copies are housed at the Library of Congress.

The Constitution's first printing is considerably rarer than even the first edition of the 1776 Declaration of Independence, Sotheby's said.

The first constitutional printing contains only the seven original articles laying out the framework for the U.S. national government and its powers, its relationship to the states and procedures used to subsequently ratify and amend the Constitution itself.

The Bill of Rights, consisting of the first 10 amendments added to the Constitution in 1791, are not included.

Although not signed, the six-page document going up for sale includes a list of the Constitutional Convention delegates attesting to its adoption in 1787 and a letter of submission from George Washington, who presided over the convention, to the Continental Congress.
