The State reported that the copy of the 1860 document will be sold Sept. 30 by Swann Auction Galleries. The auction house estimates it will sell for $10,000 to $15,000.
Rick Stattler is director of Swann's printed Americana items and says such documents are rare but have come up for sale in the past.
The original ordinance is housed at the South Carolina Archives and History Center in Columbia. About 200 lithograph copies were made of the original and the document up for auction is one of those that was passed down through generations of the family of signer Edward McGrady, a prominent Charleston lawyer.
