The 1954 film "River of No Return" features Marilyn Monroe who sings a song about a silver dollar but the coin does not appear in the film. Later she is joined by Robert Mitchum and young boy as they are forced to ride a raft down a dangerous river. The film is set in the 1870's or 1880's in the American Northwest and was filmed mostly in the Canadian National Parks of Banff and Jasper. There is a "River of No Return" in Idaho named the Salmon River, but the river in the film is not named. Added is a 2019 "River of No Return" United States commemorative quarter which has nothing to do with the film.

Marilyn Monroe is an entertainer who has been singing in a saloon in a wild Northwest mining town.

The silver dollar could be a United States Liberty Seated type or a Morgan type. Rancher Robert Mitchum has been away for some time and he returns to the town to find his son Tommy Rettig who has been running errands for Marilyn. The three meet at Marilyn's saloon.

Rory Calhoun is a professional gambler who has won or cheated a miner of a valuable gold claim. He wants to go to the county seat to file the claim and needs money, which he gets from Marilyn. They pass themselves off as married but are not.

Harry and Marilyn obtain a wooden river boat and head down the unnamed "River of No Return." Robert and Tommy are not miners but work a small ranch along the river, they head for their ranch.

Dangerous Indians live in the area and Robert has to show Tommy how to survive.

The rifle appears to be a Marlin model 1893, but that does not mean the film is set after that year. Harry and Marilyn arrive on their raft, meet Robert and Tommy. The dishonest Harry steals Robert's horse and rifle and leaves on the horse. Indians arrive and Robert, Tommy, and Marilyn get onto the raft and head down the river.

The three spend the days on the river, sometimes riding rapids, and spending the nights camping. Robert and Marilyn become closer as Marilyn regrets her choice in men.

The budding romance is broken up by an Indian attack.

The three fight off the Indians and arrive at the county seat.

Robert intends to fight or kill Harry, Marilyn visits Harry to warn him, Harry tries to shoot Robert but is shot by young Tommy. At first Marilyn resumes her singing career but then Robert convinces her to go with him and Tommy.

In 2010 the United States began minting the America the Beautiful Quarters (25 cents) commemorative series honoring national parks and wild areas. In 2019 one of the coins minted was the River of No Return Wilderness Quarter. The Wilderness is located in the State of Idaho and includes Main Salmon River and Middle Fork of the Salmon River. The Salmon River was known locally as the "River of No Return."
