Nice find and nice photos.  
You have indeed a hard to find 1992D CAM but I will leave the value up to others.

Neither look like genuine  straight clips.   
The second one you can see where the metal has folded over after the coin was struck.

Besides the W mint mark, just look at the U in UNITED, a counterfeit is straight    
on the bottom on the right hand side, a genuine coin is curved. This applies to
a lot of the years of counterfeits.

Simple answer, no.
The only 1970 small date has the S mint mark . Seeing yours has no mm, it would not be possible

We see these quite often on the forum.  
As Coinbuf stated, just a vise job or sometimes called a garage job.  
 Someone with too much time on their hands. A damaged coin now.

That is not an error, it is damage  (PMD). There is no way for that to occur when the dime was struck.

Please do not use screen shots, they are too pixilated to see small detail clearly.   
From what I can make out, it looks like zinc rot, just another damaged zincoin.

Photos are a little dark to see detail but without even looking at it I could be 99.9999%  sure it is a counterfeit.  
This is probably the second most asked question on the forum and no one has found a genuine one yet.

The same as your 2008 nickel that is severe DDD from a very worn die.

That would be Die Deterioration Doubling (DDD)
In Mechanical Doubling the devices would be reduced.

Maybe it is just me but I do not consider die chips an error, it is a die event. It is no different than die deterioration or die polishing. The die has been altered and every coin struck after the chip started would have that mark. You could have tens of thousands the same until the die was retired.  Most errors are a one time event due to improper striking of the coin. If the die has a chip, then no matter how well the coin is struck, it would still show, it has nothing to do with the improper striking of the coin. 

Thanks for the new photo. The fact that the reeds are missing and the diameter is smaller confirms my thoughts that it is a dryer coin. This is not considered an error but damage to the coin.
Suggest if you are going to look for errors, read up on what constitutes an error. Sandon has given you some websites plus this is one I use frequently.  error-ref.com.

First, never hold a coin in your bare hands, the oil from your skin can cause fingerprints and greatly devalue a coin.
Also those are not reed marks, it is a pattern around the edge of your coin. It looks like the edge has just been worn down either intentionaly or unintentionaly.
Almost forgot, welcome to the forum

Looks like it might be a small delamination.   
Also a Struck Through is not a variety, it is an error. 

Would really need to have the size. It looks like a blank of some sort.
