This episode of the television program "My Favorite Martian" features a "Martian Identity Disk" which resembles a United States dime or 10-cent coin. Also shown is a vending machine with some US silver coins in circulation in 1965. "My Favorite Martian" was a half-hour television program which ran on the CBS television network from 1963 to 1966. The program starred Ray Walston as the Martin or "Uncle Martin", and Bill Bixby as Tim O'Hara, a Los Angeles newspaper reporter. The episode is titled "Gone But Not Forgotten" and was first broadcast on March 3, 1965.

The series was about Tim O'Hara, a Los Angeles newspaper reporter, and his "Uncle Martin", a Martian who accidently landed on Earth in a spaceship, became marooned, and is living with Tim while he tries to repair his ship and return to Mars. Martin has various "magic" powers, he can read minds, levitate objects with his finger, and become invisible. He has a pair of antennae which he raises to disappear. He has brought with him or has built various fantastic machines. The series was produced by the Jack Chertok Television Productions and the CBS Television Network. In this episode, Martin loses a "Martian Identity Disk", which contains all of his personal data. The disk resembles a United States dime (10-cent coin).

Martin is hooked up to one of his devices and has an accident which causes anything his finger touches to become invisible for a short time. He drops his identity disk and has to raise his antennae to locate it.

Martin and Tim look for the device and Tim finds it.

Tim remarks that it looks like a dime. Martin explains that it is his "Martian Identity Disk", which contains all of his personal data. He needs it to get back to Mars.

Tim's apartment is decorated with modern art style paintings. Mrs. Lorelei Brown, Tim's landlady, notices some furniture items missing (they are invisible), and calls the police. Detective Phil Brennan shows up, he is a suitor of Mrs. Brown and does not get along with Tim or Martin, whom he suspects of being criminals. The furniture reappears, but Det. Brennan searches one of Martin's jackets and finds some small tools which he assumes are burglar tools. He also finds the disk which he assumes to be a valuable coin.

Det. Brennan takes the jacket and the O'Hara's to the police station. Brennan accidently spends the "dime" in a vending machine.

This 1960's vending machine would be an antique now.

Martin becomes upset as he watches his disk disappears into the machine.

Martin uses some Martian trickery to cause the machine to disgorge lots of coins.

A Washington quarter and a Jefferson nickel can be identified in this scene. At that time the quarters were made of silver. Tim finds the disk, a closer look reveals that it does not look like a dime after all.

This "prop" appears to be a small version of a "good luck" or "all-seeing eye" token. The episode ends happily, the police release Tim and Martin who head home. Martin discovers that his finger no longer causes things to disappear.
