[Mobilprojohnny]

Hi i compare this picture with Mr. Wexler's and it look almost the same but on mind, it have split on the lettering.

Hummmmk that looks like strike doubling, or worthless doubling as John Wexler calls it...

Remember, it is the die that had multiple impressions on it. Those impressions though slightly off should be at nearly the same height. There are other doubled dies that add thickness to the coins, and they can confuse people.

I always try to match up the ddo to a known verified source. Remember. These impressions were pressed into a metal die, so the impressions dont move. Then, that working die, with the doubled die is added to a minting press and it hammers out coins for the service life of the die.


Variety vista has two DDOs for that year. Mr. Wiles adds a comment above the photos that tells you where you should look for the doubled die.some of the other sites may use a cross reference number.

Thank you. So i shouldn't focus to much on splitting and notching? I look at alots of doubling on all 3 web site and some show splitting and notching. I'm just alittle lost of what to look for in doubling.

Yes, you should concentrate on the doubling and notching, but not all coins will show notching aka split serifs. I highly recommend using the three websites I mentioned above... varietyvista, coppercoins and doubleddie to try and match up the coin almost exactly to what they show in the photos.

Some people will say if there is no listing for a doubled die prior to 1996, then the coin is not one.... are placing bets that no new variety finds will happen. More than not, they are correct, but new discoveries happen, but are quite scarce.

Typically there is no "close enough" or "slop" in the majority of the doubled dies that have been documented. The attrubuters show the areas that are doubled and those areas should be the primary areas to focus on, if it does not match, it is not that doubled die.

Doubled dies, before 1996, If the coin has a mint mark, it might also aid in finding a match for the doubled die, as the mintmarks were added to the working dies later by hand after the working dies were created and finished. The different mintmark placement is key on Repunched mintmarks, but can help on attributing DDOs and DDRs.

To be candid and honest, it's going to boil down to experience, research and reading a good book on the minting process. Knowing how to differentiate between worthless doubling ( article on John Wexler site - Doubleddie.com) and a doubled die is key.

If you can find a cheap copy of

The error coin encyclopedia by Arnold Margolis

It will logically walk you through the processes and may help understanding the minting process a bit easier.

Before 1996.....Doubled dies are all unique, and there will be differences in each one. Doubled dies are typically one impression over another on the metal working die. How much separation is dependent on how off the die was placed back into the press for an additional impression ( also known as hubbing).

I have an article in my signature below which might shed some light on the differences.

Thank you. This from a 1959 d Nickels. This mint mark is D/ something. Not sure, at different angle it look like number 2. Also the words five is machine doubled?

[Mobilprojohnny]

sorry didn't attach picture. I run into alots of these lettering. remove due to Coneca rule.

[MintErrors]

CONECA staff based rules state one coin per post. I suggest you remove those nickel posts and start a new thread/post. The reason is clear; people may never see this additional coin. It helps cut down on confusion.
