Lee Harvey Oswald's Original Coffin for Sale

The original coffin of John F. Kennedy assassin Lee Harvey Oswald is up for auction. INSIDE EDITION has the details.

It's a macabre relic from one of the darkest times in American history.

Incredibly, the original coffin Lee Harvey Oswald was buried in and where he remained for almost two decades is being auctioned off to the highest bidder!

The crumbling pine coffin that once contained the man who assassinated President Kennedy now sits in the office of auction house owner Nate Sanders.

"It's coming apart because of the water deterioration when it was underground for 18 years," he tells INSIDE EDITION.

Oswald was shot to death by Jack Ruby two days after Kennedy's assassination.

He was buried in 1963 at a cemetery in Fort Worth, Texas. At the graveside were his widow Marina, and his brother and mother.  

But in 1981, Marina had the coffin exhumed in an effort to prove that it wasn't really her husband's body inside.

"It turned out he was in the casket, so they put him in a new casket," explains Sanders.

Now the original coffin is being auctioned off by the funeral home. Sanders says it could sell for $100,000 or more.

"It might give you chills because this is a coffin but this is one of the most important pieces of American memorabilia ever to be auctioned off," he tells INSIDE EDITION.

The coffin is the centerpiece of an auction of JFK memorabilia at natedsanders.com.

Also included is Oswald's original handwritten death certificate. The cause of death is listed as "shot in stomach."

The online auction is currently open, it ends December 16th.
