The coin you show would be from a coin struck shortly after the clash.  I believe the OP's coin was struck after the die was polished and just shows remnants of the original clash. Guess the only way to tell for sure would be to do an overlay which I can' do.
Also I took that photo from my file. I have a file of a couple of hundred photos that I have created over the years for my own use. If there is another Canadian coin you would like to see, I may have a photo of it.

I agree, just a die that was used well after it should have been retired.  
No value in these beyond face.

It is probably a copper cent plated with nickel, hence the attraction to a large magnet.  
If it was a steel coin, a small magnet would attract it plus it would weigh less.
Not unusual to see nickel plated coins. No value but keep it as it is from your grandmother.

Do you realize that it would cost $50 - 60.00 to have graded. 
With the split plating issues, it is worth 1 cent.

A badly damaged dryer coin. Worth 25 cents if you can get someone to accept it.

That is  what is known as a "Texas Cent" (Everything is bigger in Texas)   
Put the cent between two pieces of leather and pound it.   This will remove the copper plating and enlarge the zinc core.

There is nothing on that coin that can’t be attributed to circulation damage.  
It is only an error if it happens during the actual striking of the coin.

One thing to remember, it might not come back as a MS70. Each grader have their own standards

What you see is minor Machine Doubling, a worthless type of doubling.  
Even if it was was a true Doubled Die, there would not be enough value to have it graded.

So that we can help you better understand value of coins, why did you think it is worth getting graded?    
Unless it is worth a t least $150.00, it does not pay to get send it in. What do you see that we don’t.

 I agree   
A common half dollar worth 50 cents

I agree, damage from the crimping machine when sealing the package.
It must have been too close to the edge when being sealed.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

A Capped die or Struck Through Grease would still weigh 5.67g
The fact that it is considerably lighter indicates that it has been acid etched.

If you want to clean your coins, the only way without chancing devaluating it is to soak it in acetone.   
This will not attack the surfaces and will clean off any gunk. I usually soak my coins for 24 hrs then rinse with
distilled water and let dry. Do not in any way try rubbing it.
