I have a 1967 Canadian cent like this. Is it caused by a faulty die or double strike on the same cent?

Twocentsworth,When a blank planchet is struck by the dies, the normal procedure is for the feeders to eject the struck coin out of the collar and into a chute. If there is a malfunction and the struck coin isn't ejected, it may receive a second or third strike by the dies.

Cool...when I saw the doubling in the eye and hair, I was hopeful.  |

Thanks for the definition,it wasn't in the glossary.If it wasn't for the glossary on this site trying to sort out all the acronyms in the US coins forum would be like trying to understand my grandaughters text messages. |

Really interesting coin.How does this occur,it can't be multiple hits,as the obverse is the anvil die.Is the error in the die?is the die loose?is it something else?

I don't know to much about the hubbing and die making that the canada mint does. I just semm to find em  but I did find this out. (coinscan dot com)It says. Prior to 1980 Smaller dies such as one and ton cents required at least two separate impressions before acceptable design transfer was achieved, larger denominations took up to five hubbings. Slight varying misalignments between hubbings have resulted many types of "Doubled Dies" as known to exist by hobbyists. Edited by coindexter

Sorry castor I don't agree. A tripled die is created by multiple hubbings not from "ejection doubling", " Machine Doubling", " Strike Doubling", "shift doubling". This is a good explnation of Doubled dies vs mech.dub,str.dbl. http://doubleddie.com/144822.htmlHere is some larger pics to look at. The separation line on the E and the serif on the G there is two serifs. Die shift would not show separation of this.   Edited by coindexter

If that's MD, there is some noticeable relief to the doubling. The serif on the G doesn't look like MD, and I don't see doubled eyes or hair on MD coins.  |
