100% agree. And it’s a big coincidence the long time resident troll is in jail again when all these ramp up. 🤔

If not one and the same they are brothers, I would not be surprised if these two and others are just alts to stir the pot.

Of a completely unremarkable 1957 cent that he's having a very bad case of pareidolia with.

What are you even trying to say?  Like I said in your other post, you're off to a very bad start here.......I cannot make any sense out of what you typed.  It's completely incoherent.

Rotated the OP's first photo, but still no "D." Must have fallen off. Ahhh ---- now I see! It fell into the thread below....but now the "S" is missing....

Nope.  Not at all. No chance.  It's just a regular, old 1969-S Cent.  Might I ask why you are thinking these coins have OMMs?  There's nothing that would even suggest one in either of the coins you posted.

I think you've got it, tj!! Congrats!

Depending on how many Canadian coins you have, the Charlton guide might be an investment. It's the eh-quivalent of the Red Book and does a really good job. For the UK stuff, might just use Numista.com.
The Third Reich coins can be controversial, in that some people just don't want them around. The dealer I worked for was Jewish, and did not want them in his store at all. Couldn't blame him a bit. I offered to buy them, but he didn't want money, so I said I'd donate the amount to a Holocaust education charity. He was fine with that.

Good instinct. The path to refining it is always to ask the question: how could this have occurred at the mint? And if that question's answer is "well, truth be told, not sure exactly how it was minted to start with," that's fine--it indicates a good field for research and growth.

Yeah...I guess that's not too hard.  I should keep an eye on nickels of those dates....maybe I can find one for Greg.  
Thanks for the link, tj.

I forgot to add......best of luck finding one, though, Greg!

Hi Chester,
What you have is definitely post minting damage.  I know of no way for what you are seeing to have happened during the minting process, so it has to be damage.  As such, the coin has no value.

It's easy!

Hi Chester!
It looks like tj helped you with the U.S. and now I can help you with the Canadian.  This is a great website for Canadian coins, but keep in mind that all prices are in Canadian Dollars, not U.S. Dollars, so you'll have to do some currency conversion to determine the prices of what you have:

Good Luck!!!

I've been in this game for going on 23 years as an adult and I wouldn't know a Henning Nickel if it kicked me in the face aside from the War Nickel one! 

This could help as well with the sorting.
 

I'm with the others, Joe. SGS was a scam grading company, but you won't get in trouble for owning that coin in that slab.  If I remember correctly, PF 70 or MS 70 were the only grades SGS would actually give out, regardless of how a coin looked or the actual grade the coin was in.  That's a big part of what got them into trouble.

Amazing photo of a fingerprint, kudos.

Definately damage after it left the mint. Looks like someone was playing around with it. 

Nope.  Not even close.  Not happening.  Robert.....the answer won't change one iota by posting the same unremarkable coin multiple times.  In fact, duplicate posts are considered to be very bad etiquette around here and are frowned upon.   If you want to do well on these boards, you're off to a pretty bad start........you do enough stuff like you've done so far, you'll end up being ignored by pretty much everyone.  I think you should look over this thread before you make any more posts if you honestly want to be successful here:
