This dime almost looks copper in color I messed with the picture in order to see I circled on the dime where you can see a faint s also this dime has insane doubling
Please post an clear enlarged photo of the area above the date. The black circle you drew around the area obscures it.
circulation strike coins don't have a mintmark when they were struck at the Philadelphia Mint then. You have a clad dime, worth face value.
Remove the black circle and post a clear enlarged photo of the area where you think you see the S mintmark. I can't see it on that thumbnail photo especially with the black circle on it.
