An Error Coin Featured In A Movie

I just finished watching a movie en
titled Dear John. It was a love story about a soldier in the war in the middle east and his girl back home. Anyway, as an 8 year old, the soldier received a strange coin in change from the ice cream truck man. It was a 1970 Jefferson nickel obverse with a Memorial cent perfectly centered on the reverse. The boy's father took the coin to a pawn shop and the owner told him it was only a novelty, but did offer him $20 for it.No thanks. The coin was next taken to a coin dealer who showed the boy and his father a flyer describing the $4000 Jefferson mule. He also said to keep the coin for 100 years and it would be worth more thna $4000 then. From then on the father became a fanatic about collecting coins. He was considered strange because he spent most of his time fussing over his collection and attending coin shows. I think some of us can relate to that!
The mule coin was not protected in any way except to be housed in a special box. It was still handled by people wearing white gloves.
At the end of the story the father dies and the son takes the coin back to war and uses it as a "flipper" to decide which way to go at a fork in the road. The coin is flipped and lands in the sand-ouch. Of course the squad went the wrong way and got shot up. The coin is finally sold to the coin dealer to pay for medical treatment for the soldier's true love's husband(she sent him a "Dear John"-hence the name of the movie.
There have been other coins featured in movies-actually TV. On "Las Vegas" an 1895 Morgan and 1943 copper cent were featured, of course both with no protective holders. I've got a better one than that. Way back in the 70s, a Hawaii Five O episode featured a 1913 V nickel, switched for a fake at a coin show. It was dropped into a newspaper vending machine to be hidden-ouch again. WOW, I didn't realize this was going to be such a long dissertation-sorry.
