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.

I think “erosion around the mintmark” would be correct.

Before anyone can help, we will require a clear photo of both sides of each coin you    
have a question about. To avoid confusion, only one coin per post please.   
Also a clear explanation of what you want to know about each coin.   
Looking forward to seeing your pictures.

A die clash would be raised and I don’t really see that on your coin.  
There might be a bit ghosting  though.

From photo supplied I am not seeing the extra V.  
Can you take a clear closeup of that area.

Another of my PO1 lowballs.   
CanadIan 1936 Silver dollar

To me pictures are not clear even to authentic either way.   
We have to be able to see all the detail such as in the photo that EagleRJO supplied.

Not a split planchet or any other error.   
You don’t show the whole coin but it is too worn to see any of the markers indicating a 1888/7.

Nice, a retained laminate that has been partiially peeled back.

A lamination is generally (to cover myself, I say generally because there have been rare cases of lamination on clad coins) restricted to solid alloy coins as it is caused by the presence of contaminants or impurities in the alloy which separate when the planchet is made. They can be small or run the full length of the coin.

A weak strike is a common problem on the reverse of Lincoln Memorials.   
To put it simply, the amount of material used to fill in Lincoln’s head leaves little
left to fill in the reverse properly.
