I watched Road to Perdition, set in 1938, recently. Coins appearing were correct. A Peace dollar was used to pay a kid and someone twirled a Walking Liberty half in their fingers at a bar. I didn't get a good look at the quarters on someone's eyes. Of course, the reason they were correct was that the prop department sourced them from Harlan J. Berk in Chicago and Tom DeLorey made sure they were set up with the right coins.
In "High School Caesar" the main character carries and shows a United States Liberty Head $20 gold coin.
Last night ME TV ran an episode of the Twilight Zone that featured a man addicted to a Vegas slot machine and numerous Morgan Silver Dollars. even ends with a Morgan rolling up to his dead body. James
