Well, hello there, treasure hunter! It seems you've stumbled upon a 1946 Roosevelt dime, the very first year they were minted. Before you get too excited and try to spend it at the candy store, let's talk value. The short answer is: it's worth a whole lot more than ten cents.
At the very least, your dime is a tiny silver ingot in disguise. Dimes made in 1946 are 90% silver, so their base value is tied to the daily whims of the silver market. This "melt value" usually hovers somewhere between $1.50 and $2.50. Not bad for something you might find in an old coat pocket!
However, the plot thickens when we talk about collector value. This is where condition is king. Does your dime look like it's been through a few dozen washing machines and paid for a thousand sodas? If so, it's likely worth its silver value. But if it looks crisp, shiny, and almost brand new, collectors will pay a premium.
You should also check for a mint mark on the reverse side, near the bottom of the torch. A "D" is for the Denver mint, an "S" is for San Francisco, and no mark at all means it was born in Philadelphia. A common, circulated 1946 dime from any mint will typically fetch you $2 to $4. If you have a brilliant, uncirculated specimen, the value can easily jump to $10 or more.
The Greysheet link you found is the perfect place for a coin nerd to get specific pricing based on official grades, which is exactly where you want to look for precise values. As for that YouTube link, it appears to be more interested in its own terms and conditions than in your numismatic query, so we can safely say it contributed nothing of value.
So, take a closer look at your dime. It's not a lottery ticket, but it's a neat piece of silver history that's certainly worth more than its face value.
