If you are so sure, then put up the money to have it attributed by one of the third party graders.
A normal cent weighs 2.5 grams. The weight of the plating could vary depending on thickness but would add very little.
Your coin has been plated at some time after it left the mint, they turn up frequently here on the forum.
If you have one that is the same, then you have a dime that just happened to be damaged in the same way. There is no way that could have happened...
Yup, just glue or something stuck on the coin.
Both coins are just damaged. The zinc was exposed on the 1990 and is corroding away. Hard to say exactly what happened to the 1981 but...
Agreed, definitely just damaged.
Yes, just one sign of cleaning. There are many others. Hang around, read a lot of posts and you'll be picking up lots of info without even...
Hey, we all start somewhere! Take a look at your first picture of the reverse. Notice around the lettering and devices is a little dirty, but in...

I would have to say that coin is definitely not uncirculated. There is wear, and in addition it looks to me like it was improperly cleaned.
1804 dollar is one of the great rarities in US numismatics. One is worth whatever it brings at auction, most likely into the millions. It is...
Definitely post some pictures, but unless you found it in a proof set there is virtually no chance it is a proof no S.
It may be the zinc core of the coin showing. Cents from mid 1982 on are made of zinc with a thin copper plating.
I'm not seeing any mint mark.
About all you can do is a careful soak in some acetone. If it is glue residue the acetone should remove it. A careful soak, rinse with clean...
The fact that it is not as worn as the rest of the coin is further proof that it happened more recently. It is just a deep gouge.
Just heavily worn with lots of dings and scratches. That one has been around!
It is a cast replica, they have been selling these for years in historic site and museum souvenir shops.
Just a dollar. Normal for 1980, the "wide or narrow" only applies to 1979.
