I found this dime as is in my pocket change. A regular dime is in the picture for comparison. What do you think? Any value in these? Thank you. I added photos but am new to the site so I hope they show up

All copper? or just on the edge? That would be something if it all copper. Cant see it but, maybe a pennie blank got mixed with the dime blanks in 2014, but then it would be a 97.5 percent zinc and 2.5 percent copper (copper-plated zinc) dime.
Still would be worth a good amount of money to certain collectors.
Oh and DONT clean it at all. If its truly a dime on pennie blank.

If, indeed, the coin has a copper appearance throughout, the most likely explanation is environmental exposure. There are many conditions that can cause the .750/.250 cupronickel cladding to take on a copper appearance.
If the planchette is solid copper, weighing it will not help significantly. With copper density at 8.94gm/cc and nickel at 8.908gm/cc, even a solid copper planchette would likely be within weight tolerance for a dime.
The likelihood of a dime sized copper plated zinc planchette showing up is so remote that the idea should be dismissed without consideration. If a cent planchette was struck with dime dies, the diameter would be cent size, not dime, and would have a near zero chance of occurance.
There are several sayings that sum up my opinion that the simplest explanation is nearly always correct.
Time for more coffee.

Chances are it's either been in a tumbler with copper cents or it's been buried in the ground for awhile.

Its could be Environmental exposure.
But it also could be something else.
How the Copper Dime Appeared
Dimes are made primarily of copper, and are coated with a mixture of copper and nickel to give the coin the appearance of a shiny silver surface. When the copper-nickel mixture wears off, the coin exposes its copper under layer, thus the brownish color of its surface.
This occurrence is considered an error, as the silver surface is not supposed to wear off. This error is called the clad coin. The non-adherence of the topmost layer of the copper dime is caused by gas and debris getting in between the layers, causing the topmost layer to separate during the lamination of the coin.
There have been instances when the topmost layer of nickel and copper mixture did not adhere on both sides of the dime, but it rarely happens. Usually only one of the sides, either the obverse or the reverse, fails to make the nickel layer adhere to the surface of the coin.
Before the dimes are distributed for circulation, they are examined if clad coins are included, and they are removed. So when a coin or two escapes from the watchful eyes of the people in the United States Mint and gets out into circulation, they are regarded rare and have higher values than what they are really worth, which is ten cents.

Dont get too excited though, still only worth $5 or $6 bucks if indeed this is the case.
But i think i see some silver on that one so this may not be the case.

Sometime before 1978 I found a clad dime in pocket change that WAS exposed copper, except for Rosie's head and the center of the reverse... those were both silver. NOT environmental damage or exposure. I did a 'horse trade' with a detector dealer with a bunch of coins I had accumulated during childhood for a Garrett BFO detector. I remember the dealer gave me $15 credit towards the detector for the dime. Wish I had kept it, but at the time I really wanted a metal detector and thought I was getting a deal.

Looks like heat treatment to me. Someone put it in an oven or something. High heat will make that kind of coloring.

The toning could have happened anytime and anywhere the coin has been since it left the Mint. There are a large array of environmental contaminants and other things that could have caused such toning. You would not believe the large variety of colors and conditions I have seen on coins in the 45+ plus years I have collecting, searching, researching, buying, selling and trading coins!
