It’s a zinc coin. You can see it on the reverse where the copper has been removed.

Total PMD.   
There is nothing on that coin that could occur while it was being struck in the coining press.  
It doesn’t really matter how the damage happened, all that matters is that it could not have    
happened when the coin was minted.

It doesn’t look like a RPM, the mm is too low to be any of the recorded 14 RPM’s.   
I think what you are seeing damage that has flattened the D and scraped the field.
Also do not let the opinion of a few dissuade you from continuing to post. I remember
when you first started posting and your knowledge of coins has come a long way since    
then by asking questions. I for one would never tell someone to stop posting, that is the
job of the moderators. If someone doesn’t want to read a post, then either ignore it or block
that person. I know that I just ignore opening the posting of a couple of members on this and
other sites. Looking forward to see what you have next for us to look at.

Welcome to the forum.
As noted, just a damaged dime, probably intentional.   
Still worth 10 cents, even in that condition.

Not an error.   
Those are called Die Chips, a part  of the minting process and are quite common.
They add no value to the coin.

I have seen that rippled effect on a blowtorched cent. You have to keep the torch moving. 
in order to not melt the copper. It would also be damage, not an error.

A second area to look at is the bottom of the 3, see how a genuine 3/2 has a bit of extra metal.  
that is lacking in your coin.

Unless you think that cent is worth about $200.00, then no, it is not worth getting graded.  
Being less than .5g underweight does not make it collectible.

Looks like your 2 for 2 Hinkle. Another good find.

Agree with the 1807 being a fake. 
As stated, a clear photo of both sides of the 1870 will be required
but if it has no motto, then it also is a fake as the last year for the    
No Motto was 1865

Looks like you found a  RPM. 
Matches 004

Welcome to the Chat Board
First, that is a Large Date 1982. Also those marks are not doubling, they look like they have taken a hit displacing the metal which would make it damage.
 

I voted Environmental Damage

I was going to admonish you for holding the coin in your hand but seeing it is a counterfeit,   
lit doesn’t really matter now. Date is wrong, Mint Mark too big and in wrong location.

Then go ahead and get it certified and let us know the results.
Sandon has supplied you with instructions and cost to get it graded.

Unusual to find even in Canada silver in change.   
The 1966 quarter would be 80% silver

Don’t forget there is a mint tolerance of .19g so yours is still within tolerance.
