Try Vicky large cents for a life-long pastime.

Yep, looks like it

Is there a thin coating on it? It looks like some of the lettering is fainter than the rest. DFidn't leave the mint that way.

It just looks to me like the Vicky grunge that someone didn't get all out when they tried to clean it. Is it hard like metal or like the remaining grit/grunge around it? Whatever it is, it's in the lower loop of the first one as well and light colored.

It's not a "double or doubled die". It's the result of die deterioration doubling from the die wearing out. It's not a variety or an error and adds no value to the coin.

Just someone's magic marker or pen. Spend it

It looks like the same type of depression is evident from the anter rack on the left and the denticles. I think that the coin had been struck with a non-sharp ridged element, probably with a hammer on top of leather, with the Obverse also shielded by leather, so nothing appears there. PMD

Is the black circle something that you did with a pen? I don't understand or see where the minted "zero" came from or it the light colored oval inside the black?

I have pulled this from another site and you all should listen to a friend of mine on an over 1 hour podcast on Canadian Counterfeit coins, starting with the miliions and millions of toonies. Mike had been a friend of mine for 25 years and he is famous with his counterfeiting education with the RCMP...

Die chip ... not part of the mint procedure

Looks like a strike-thru to me but don't know what it was caught on the die maybe a rim fin. The mark runs over some of the design, leaving a recessed mark on the coin, but it is under some of the design (the leaf stem) so it doesn't show into the design. Then the stem tip broke whatever it was, so ...

It looks like a "dryer coin" and the weight is less because one side almost worn away and just .13 g from fully struck, probably still within original tollerance, but the wear itself reduces the weight.

It was a special commem honoring the RCMP. I think only in silver and maybe not in circulation; just a commem to buy from the RCM. Your cxoin looks like it no longer an untouched spec or proof or P/L. Not worth grading https://www.coinsandcanada.com/coins-auctions-prices.php?denomination=7&date=1973...

Yes, they used the dies until they were ready to break in pieces. If you think about how thin the little cogs of metal would be on the master used to strike and make the dies, you can see how many serifs broke off. Rather than make new dies they, would handpunch letters and numbers into the dies to ...
