Mr Wilson is very proud to show Dennis a new acquisition to his coin collection, a 1919-D dime. This United States coin is a Winged Liberty Head Dime, also called a Mercury Dime. When the actual coin is shown on camera, viewers are incorrectly shown a Barber Dime, which was last minted in 1916. Only 9,939,000 1919-D dimes were produced and in 2018 this coin could be worth more than $20,000 if in excellent mint state condition.
The 1919D dime mention by Mr. Wilson is a Mercury dime, not that Barber dime shown later. It is also not especially valuable.
