Whatever anyone says, this coin IS a coin with a story - the best kind, in my opinion. This coin is from the beginning of the era of cupronickel coinage. Do some reading on Joseph Wharton, namesake of the Wharton School of Business at Penn, and how he turned a played out copper mine in eastern Lancaster County, Pennsylvania, and his political connections, into the era of "nickels". It's a neat story.
I don't know, I like it. It's a survivor. If you want to try to bring up the date, and that's right under the shield, soak it in white vinegar for several hours, then look at it under magnification and see if you can make out that last digit. The dates are quite small on these, so it's a longshot. The composition is the same as that of the Buffalo Nickel, and white vinegar brings up dates on those, thus, why I'm recommending it. It won't ruin the coin, don't worry none about that.
Relatively speaking, it was worth a lot more on the day it was minted than it is today. In 1866 or 1867, you could buy a lot of stuff with a nickel!
