Different "0" in 1980 Canadian Dime

Also I found a 1980 quarter with a perfect flat outside edge. Feeling the rim I can't feel any kind of reeded edge that used to be there. Is this quarter really worn out or is this a variety? Thank-you.

Thank-you for the link! Very helpful. CHEERS!

That is another very good observation. I like it too! Thank-you.

@coingirl- You're mistaking errors for varieties. There are a lot of variety collectors and they have just as much fun looking for the differences as error collectors do looking for mistakes.

coingirl,you've planted the seed of misinformation,to suggest that the Mint purposely produces errors or varieties of circulation coins for profit is preposterous.

DBM,
can you then please explain how come they manage to constantly make "artificial" mistakes?
please remember this: they use the latest technology in machinery, design criteria and, software which is close to fool proof.
example: theit SW will pick up when a coin is accidentially stuck and it stops the machines right there. the coin is / should be ejected into a special bin It is now the attendants (more that 1) job to remove any and all not correctly struck items. If they do not reemove it and let a dbl struck coin go into circulation (backdoor does not work anymore), is that now an error, a variety, or a simple illegal action?
(IMO, It is most certainly NOT a variety, as a variety is purposely made different than the other.)

BUT, there is an immediate record created by SW, KNOWING THE EXACT NUMBER OF COINS INVOLVED. I suggest that the mint does close both eyes purposely to create attention amongst collectors.
the same goes for die rotated coins. Coins in the new machines do very seldom rotate anymore, and if they do, it is so minimal. SO, that, IMO leaves only on conclusion: it is done by choice... and hence NOT an error.
remember the fiasko with the 1967 dbl struck and flipped dollars? and the 1973 / 1974 10$ Mule? ... the RCMP investigated both cases....
none should have ever left the mint..at that time, nobody could or wanted to explain... they had backdoors then where dealers or friends were conveniently walking by....
Have you, or anyone else seen any significant normally occuring "ERRORS" since?
Maybe a few very tiny die breaks...again, SW and sensors detect it now...Clipped coins, maybe a few.. but should again NOT have left the mint...
there are a few , very few true errors which are not detectable with SW or normal Quality control du to high volume. but they are few.
Is a different font a Error? NO.....
I probably had one of the last real errors...the 1985 NZ Mule 1$ nickel. Machinery and SW in 1985 was antique compared to todays.
enough from me on this... these items are not really my interest.
DBM, if you have another explanation, lets hear it.
and please... do not try and suggest that the mint has a stellar reputation....

"to suggest that the Mint purposely produces errors or varieties of circulation coins for profit is preposterous"

To this all I can say is 2006 1 cent, or should that be all 6 2006 1 cents?

Scissel...
Are you suggesting that the sets are NOT money?
