1979 DDD 979, Worth A 2×2?

I would give it a 100% pure acetone bath and then 2x2 it.

@coop, I first though DDR but when I researched this year on coins and Canada it has the double date variety listed for the date, I read another thread on here with a 1979 dime with the same doubling, I think this one's listed as DDO I'll post the thread link

@ coop, here is a shot from the opposite angle, idk if it will help but figure a second angle can't hurt




I am not sure how to tell the difference between Doubled dies and DDD, I think the 1979 penny with doubling on the date has been confirmed as DDD, but who knows. Would be cool to find my first doubled die but once I read the other thread I posted I wrote this off as a DDD, a cool example of DDD unless it is a true double die.

@john1, thank you:)

Coop, the 1962 cent you have shown here is the result of Die Deterioration Doubling, same with the 1979 cent shown by the OP.

Most of the time when deterioration on Canadian small cents kicks in it works its way from the center outward, for example.

1979 deterioration doubling's progression.

- 1979 "Double 9"
- 1979 "Double 79"
- 1979 "Double 979"
- 1979 "Double Full Date"

A genuine doubled die does not go through a progression phase like the example for 1979 written above, when hub doubled designs or dates are present they are restricted and exact every time the affected die strikes a coin.

Compared to US Lincoln cents, Canadian 1 cent coins feature many differences from the size of devices, the edges of the devices, and larger areas with detail, all play a part in how deterioration can affect them.

Here is a perfect example of Die Deterioration Doubling on the reverse of this 1967 cent with full date doubling, similar to coops 1962.

You are the collector. If you like it, keep it.

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.
