I have a request to make of one of you members: Does any one have a proof 1979 cent? I need to obtain one for the purpose of making a layover, which will demonstrate the need for, and to adentify the portions that are seen, after a clashed die occurs. The coin will be returned ASAP, and I will guarantee the safe comdition, as it was received, what ever the cost. I think this is a worthy cause, and I am willing to take the risk of anything that might happen to said coin. Anyone? Comments? Opionions?

If this comes ouit, it is what I am trying to demonstrate:  All credits go to coppercoins.com, and to Richard S. Cooper for the photos, and comments seen. The purpose of this photo is to show the benefits one can derive by having this overlay "handy". Coop has agreed to make the overlay, if a proof 1979 CANADIAN CENT CAN BE OBTAINED.

Dick,
DO you need obverse and reverse of 1979? I posted the reverse on the other thread.

Marc, I have been doing battle with PS 7.0, and trying to make a similar overlay, like the one I posted of the US cent. I have several 1979 cents, not including the one with the "a[pparent die clash, "which prompted this thread in the first place), and some MD's. They are just circulated coins, and while a proof would be best, I believe the circulated ones will define the aeras in question. At least, they are what I have to work with. Now If O knew how to do the overlays, (without having to start from scratch, over, and over, ad nausium!

No problem Dick I can do the overlay if you tell me exactly what I should do. I also have several 1979 pennies in mighty MS so just tell me the steps.

Marc, I can't tell you the steps, but I can give you a lead to the "master of the tricks": Go to coppercoins.com, and under world copper, check Kurts Bhutan coin. In that thread you will find three links to the :overlay scenario, all by Coop. I'm still trying to learn to do them, (without much success)!

All right Dick I'll give this a try. Is the idea to get a translucent image of the reverse onto the obverse?
I looked at some other 1979 pennies and I have many that exhibit doubling of the forehead, nose and back. I have some doubts that overlay will reveal anything with those specific defects.

Marc, that is the reason for the particular type of over lay. It shows you what is where, and confirms, or denies the clash.
Fast question: What is a good bid on 1909-1920 series of cents?
You may email: azbrushape@aol.com
Dick
Edit: There seems to be some question whether it might be a "chip- out on the die, which would leave a high spot where the missing piece was... The only thing, with that line of thought, is: how did it happen in so many places, at the same time?

Hi Dick,
In VG/F+ range large cents 1911-1920 you are looking at approx. $1-$2. Edward VII are $3-$5 with 1907H around $20.
The chip-out theory is possible but here is what I think might have happened. 1979 saw a change in the portrait so the Mint had to create new dies. The process is quite complex and uses reduction instruments that replicate the initial "large" portrait down to smaller "positive" ones that eventually are used to create the dies or the "negatives". Several dies are created from one positive "hallmark" as it is made of hardened material. My guess is that one positive hallmark deteriorated rapidly and created several dies of increasing degree of defect. Those dies were then used to produce the coins, thus faithfully reproducing the same defects for each die.

Marc, that could very well be true. I won't argue the point., other than to comment on the four places that the anomily occurs. The back of the neck, the bridge og the nose, front of the upper lip, and front of the throat. The back of the neck, and bridge of the nose, possibly, due to the configuration, but under the chin, and under the nose, I don't think that is the cause. My ecperience with clashes, is small, because I have only been "digging" into the clashes, and how they are (I can'T see what I'm saying, so bear with me). The overlays show the changes made to any part of the devices, and/or design, or portrait. It also shows where each component of the opposite die contacts the othe, and leaves it's mark. It has been very useful for determining which die produced what coin, when you have two, or three that look alike, except for the markers, and you aren't sure which iswhich. I hace not seen it used on Canadian "coins", so I don't know that much about it. And my very limited experience with Canadian cents, (which is all I collect, at the moment. Hence the Need, (mine, at least for determining what did what, where), to provide this info, or method of determining what happened that year, (1979).
I am just learning the procedure, and DON'T have it down pat. In fact, I can't do one, and be satisfied with it, yet! Over time, I'll get the "hang of it", and produce one. Happy Easter!

Marc, I just received the coins that are the topic of this current discussion, ( the large cents, 1900-1920, inc. I have the '01, '03, and the '09-'20 They appear to be in better grade than were advertised. I don't grade coins, in general, US, or Canadian,so I'm no authority. However the appearance is very nice, and much better than some similar coins of that area that I recently received. I am quite satisfied with them!

Dick I could not explain this defect with overlay (die clash) as I did in the other thread... This is a 1979 penny showing a double forehead. MDD?   Marc Edited by canadian_coins
