1979 DDD 979, Worth A 2×2?

The 1967 doubled die recognized by PCGS is a Doubled Die Obverse and can be found on the legend "D.G. REGINA" I have a few posts with a couple of my examples here on the coin community forum, SPP-Ottawa was the one that sent in his example of the 1967 DDO and had it successfully recognized and attributed by PCGS as far as I'm aware.

I have a few examples of the 1967 DDO but not in high enough grade for me to send one in, I've sold a few in the past as well.

Doubled Dies can, and sometimes DO show Machine Doubling or Die Deterioration, sometimes even both.

During the hubbing process when an Obverse or Reverse working die is created, the working punch (raised on the die) is hubbed against the blank working die more than once.


Normal working die creation:

1 - The first hubbing impression from the working punch in the correct orientation.
2 - The second hubbing impression from the working punch in the correct orientation.
= Coins struck perfectly with no doubled elements.


Hub Doubled working die creation:

1 - The first hubbing impression from the working punch in the correct orientation.
2 - The second hubbing impression from the working punch slightly rotated, offset or misaligned.
= Coins struck with notching, split serifs, extra details etc.


When there is a rotation, offset or misalignment present from the second hubbing impression it can leave what is commonly known as the "spread" (the distance between the two impressions) and they can be easily recognized by looking for things like Split serifs or notching and on occasion completely seprate yet identicle details (like the extra claw on the 5 cent DDR's).

A Doubled Working Die is exactly the same as a normal working die besides having hub doubled elements and it can still deteriorate, age, and fall subject to minor Machine Doubling when striking coins.

A different story to whom? That's a matter of perspective. Preserving for your own enjoyment, absolutely yes. But this sort Die Deterioration Doubling is very common on the dates of the 1977, 1978 and 1979 1c coins. MS-65 and MS-66 graded examples do fetch a bit of premium, for example, you can buy this one for $40: https://www.ebay.ca/itm/184861088902 (subtract the $10 cost of grading and add $5 for shipping) and a MS-66 of this Die Deterioration Doubling variant is worth about $35. Lower grades, the prices drop drastically.

I have sold entire BU coin tubes of the 1979, with the 979 doubled for $12.50 (50 coins at 25 cents a coin). AU and circulated examples I don't even bother keeping.

So again, if you like it, keep it and put in a 2x2. The hunt is part of the hobby and fun, and so too is the hunt for upgrades.

@SPPOttawa, I just mean if these are fairly common, if I put every Die Deterioration example I find I'd be saving half the coins I look at lol, so I save the best examples in the best condition I can find. If I found a full date DDD I'd probably throw this one back in the searched pile. I will save all the different varieties I find, like the 67 DDD I just found, but I'll be saving one of each for Die Deterioration album and then a variety album I will start with as many different ones I can find.(this isn't a variety per say) I'll be keeping every coin I post for a while and ones I don't post(untill I find a bank that will allow me to trade penny rolls for different penny rolls.

Wrekkdd, the 1962 that coop shows is Die Deterioration, there is no known doubled die for that year.

Doubled died date they have that listed as.

Thanks John for your detailed explanation of the hubbing process and explanation of how different doubling that occurs!

Coinman91, no problem at all.

Wrekkdd, if you look on the main listing page here https://www.coinsandcanada.com/coin...nt-1953-1964 you will notice that they fixed it and refer to it as "double 962" and not doubled die.

You will also notice if you click "1962 - Double 962" they dont mention doubled die at all on the listing page, only "Double 962" which was previously "Doubled Die Date".

As for a list of all known genuine doubled dies, there isent one, other than the one in my book (literally the whole purpose of me writing it) you wont find a complete list that only shows genuine hub doubled varieties.

The Charlton 70th edition catalogue has a small cent variety section (written by SPP-Ottawa) in the back with a couple doubled die examples being mentioned, I'm sure if he had more space/time to fill it in at that point he would have but I dont think he was given a lot of space or time to do so, not entirely sure on that.
