Brass knuckles are a rare piece of Americana, and the Smithsonian has been collecting them for a long time.
Now the Smithsonian says it has the chance to keep them in the museum’s collection, but it’s unclear when.
The museum has held a public auction for the knuckles since late May, but no one has bid on them yet.
It’s unclear if the auction will take place before the end of June.
The Knuckles are in the National Firearms Museum collection.
They are a relic of the Civil War, and were given to the museum by the Confederate States of America as a reminder of the loss of life in the conflict.
They were originally engraved with the initials of the Confederate general George McClellan, and are in a special section of the National Historic Landmark.
When asked for comment, the Smithsonian told the Associated Press: “The Knuckle is currently in the possession of the Smithsonian Institution.
We can’t say when the auction is scheduled or what will be at auction, but we hope to announce it in the coming weeks.”
The museum is looking to sell the knuckle at auction in 2019.
It is not known how much the Knuckles would fetch.
