First the condition looks like it is uncirculated I don't see any scratches on it so it looks possibly might be a proof coin.
I t looks like a nice BU Roosevelt dime but can't be a proof coin. Since 1968 all proof coins were made in the San Francisco Branch of the US Mint. All coins have the S mint mark except the error "No S" coins. If you post a clear photo of both sides of your coin it would help us give an opinion on the grade.
That is called toning. Clad coins change color. Normal natural toning. Environmental toning. Any other questions? I've been collecting coins for 34 years now. Especially mint errors!
Probably thousands.. Let me ask you this.. Have you ever seen anyone with this size Mint Error collection? 34 years worth.. Graded, attributed and certified! And I have hundreds more in albums.. You are talking to a genuine specialist. Any more questions?
I'm also a Metal Detecting enthusiast. Over the years I have found thousands of clad coins and nickels with environmental damage. Dark, gold, brown all sorts of colors!
One question do you have nightmares about coins attacking you. Very impressive but my wife would kill me if I ever got that serious. Thanks for giving me a tour about your collection fantastic U the man.
coins are made of metal. What happens when metal is not protected, such as what happens to cars if their steel bodies were not painted or other coatings? They rust. What happens to copper trimmings on houses over time if not maintained? It starts corroding and turns green. What happens to nickel, zinc, etc over time ? they corrode, get toned due to the metal being exposed to certain scenarios. If you start inventorying *all* of the change that you get you will start seeing this discoloration of various types very often.
Thank you. I really apreciate your answer to my question. Is it rare by chance and does it give my coin any value?
