A Coffin Full of Dollars is a book written by Joe Millard and the first in a series of novels regarding further adventures of the man with no name.
While bringing in the body of Marvin "No Nose" Megley to the Sheriff of Los Ydros, the Man with No Name (maybe named Manco) witnesses the circus coming into town, a family circus ringled by pickpocket and gambler Dandy Deever.
After buying his ticket to the circus, figuring they'd need protection, Manco spots his old rival Shadrach in the audience. Shadrach, whom Manco had only previously known by reputation, had stolen Manco's bounties and left as little as $10 for his assistance. Shadrach and Manco vowed to kill each other on sight.
During the show, some outlaws led by One-Eye Previs cause trouble and threaten to molest Dandy's wife, Molly, and his daughter Laura. Manco kills the outlaws, due to Shadrach being too held back by the audience to help, and is offered a chance to travel with them and perform a shooting act with them.
While in the Deevers' stagecoach, Manco learns that the girl he saved wasn't really Laura, but her twin sister Cora, who performed the illusion of Laura disappearing inside a coffin.
As he travels with them, Manco's shooting act is interrupted by the arrival of the bandit Apachito, a sadistic murderer who kills his victims slowly. As Apachito threatens Manco, he's chased away by the circus lion, who is toothless and declawed anyway. Shadrach shows up at the circus to try and get his bounty on Apachito, but he and Manco are forced to work together when the bandit escapes.
During his tour, Manco takes a detour into the town of Hangville, a safe haven for criminals, and witnesses a fight started by the outlaw Curley Bick. He investigates more of the town, nearly gets arrested, and escapes. Arriving back at the circus, he learns that Curley had followed him and kills him for the $1,500 bounty.
Manco, Shadrach and the Deevers learn from the President of the Bank of Hangville that Apachito is on his way to rob the bank, so they arrange for the money to be evacuated.
They get the money out, but the wagon carrying it breaks, so they think of another way to transport it. They ease the money into the coffin, but Apachito is hot on their heels.
Suddenly a flash flood breaks out. Still thinking the money is in the coffin, Manco and Shadrach chase after it, but realize it was a decoy and Dandy got away with the money.
