There was also an episode of the Amos & Andy show that involved a rare nickel.
Andy found an 1877 nickel, and contacted a rare coin dealer to find out if it was valuable. The dealer wrote back to him that he was interested in buying it for $250. The Kingfish intercepted the letter, and concocted an elaborate scheme to separate the nickel from Andy. Once he got the nickel, he called the dealer, and then realized that he had put the nickel into the pay phone. He confessed to Andy, and they agreed to split the profit if they could get the nickel back.
The two of them tried to break into the coin box while a plainclothes cop happened to be standing outside the booth waiting to use the phone. They were arrested, and pleaded their case before the judge. The judge believed their story, gave them a stern lecture, and they walked out free men with the nickel.
The Kingfish insisted that Andy should call the coin dealer from the phone right outside of the courtroom. Andy put the rare nickel into the phone and dialed the number. He told the Kingfish what he had done, and his friend walked away in anger.
But Andy had outsmarted his conniving friend by intentionally dialing a non-working number, and got the nickel back when he hung up the phone.
