Hey All!I have been looking at this coin for a while trying to figure out what type of error it has? The obverse looks as though it was struck twice.To the right of Her nose,chin,forehead and D.G.REGIN.Also LIZABETH II,and the dots going around the top. The reverse has what looks like doubled die on all lettering,Canada,the Dollar and the 68 of 1968. Is this a common coin,or does it hold some value?      |

Flat field doubling...

OK,that explains the obverse,but,what about the reverse?It has clear notching,of the left side,of "Dollar"?From what I've read about here on CCF is,if it has notching,then it would be a doubled die.Or have I missed something along the line here?  |

There are two doubled dies for 1968, as well as a huge array of machine doubled elements and flat field doubling. Unknown to me, PCGS just recently both doubled dies to their circulation nickel dollar registry. http://www.PCGS.com/SetRegistry/set....aspx?c=3063There _is_ a visible difference between the two, which will be clearly shown in an upcoming column in the CN Journal (Canadian Spice).

I may agree with flat field doubling but my problem is the description you find on the internet on how it is formed. On a proof, the flat field doubling is form because of the slight difference in the necessary second or more strikes required. It makes sense for a proof but it is not the case with a business strike! For business strike, it is indicated that it is produced when the die/blank first makes contacts, slightly before the full pressure is applied. When I compared the few 1968 dollars that had this error, I found the doubling aligns perfectly from one coin to another. The likely hood that this would occur, due to what is referred as "slop" in the press, is in my view, impossible. If I have two balls of Playdoo and step on them, the flatten balls will look similar but not the same! So, how can a shift of the die produce a flatten outline that always looks exactly the same way? Here is a picture that SPP presented here ( https://goccf.com/t/198695 ) and the picture presented above (rotated and cropped). Note how the doubling looks exactly the same (to me). So how is this possible based on the tradition definition of flat field doubling ( http://www.error-ref.com/flat-field-doubling/ ) ?  |

hello Cross-eyed. you photo are excellent. ok these are business strikes. if you take a close look at these coins. you will see that they are not the same. yours is doubled on Elizabeth. my coin is not. there are variable differences on the 3 other coins as well. so no I dont think any of them are a perfect copy of one another. now there may be doubles out there. the only way to know would be. to see how many are certified. if people shared images we could all see the differences.

Great pictures Rocky. It enabled me to get a closer look at ELIZABETH and there are hints that the doubling also exist on your coin, much like the one on cross-eyed's coin. So I am a bit puzzled by your reply  |

yes you are right but not as strong as crosseyed coin. its is only a couple of slightly doubled letters. one of the coins I checked for another collector from the club. his coin was completely doubled with shift. even the reverse had the strongest doubling. I have seen on a 1968 nickel dollar. that is why from what I have seen. they have slight variations. could they have duplicate probably do. thank you

numidan I was reading on these 1968 nickel dollars. a dealer out west has listed. the 1968 nickel dollar with a ghost on the island. I am wondering have you or anyone else ever seen one of these coins. do you know what this ghost looks like. I tried to message the dealer but no response. I would like to see one of them coins. even some photos would be nice. if one can photograph this ghost. so we could know what to look for. have a great one

Interesting that all of the dollars shown here have rolling marks.
What percentage of '68 dollars have rolling marks.
"Dipping" is not considered cleaning...

I think the rolling marks are common, mine has them too. I remember posting a pic of mine in a thread but I can't find it now.

When I found this coin,I was so excited that I didn't check out the other one I had.Coin #2,I think is closer to Rocky's coin than the first one I posted. #2      numidan makes a good point though,IMHO,if BS are only struck once,then how can it be Flat field doubling? Quote:
