1995 D Cent DDO DDR?

[Novicetoerr]

Thanks!

- I have a number of 1995 coins where this bump seemed
to be moving in counter clockwise (and left upwards
directions) and decreasing its magnitude.
Is this a typical characteristic of MDD?

Thanks,
J

Yes. there would be no variation if it were a doubled die. Each coin would be identical. The fact that it is not identical on each coin is a prime reason to declare it machine doubling.

Hi,

I am not sure if your question means all at the same time or separately.

Separately, yes. BUT to a point:-) The processes of hubbing has changed over the years and some things that were possible on earlier coins do not happen the same way today.

As to all those things happening together, this is theoretical.

Morgan dollars often had as many as twelve impressions made from a hub into die steel to create a die so that all the minute details would be transfered from the hub to the die.

So theoretically, what you describe such as, "counterclockwise rotation + left upward offset + re-alignment to correct " could all be on the same coin if the process including many impressions of a hub to make a die.

It would be left up to the folks that really dig into those things to tell us if any such coin exists that would have been struck by a die that was that fouled up:-)

All that stuff would not happen together on todays coinage.

I am not sure if that is what you are trying to ask as the question was a little vague.

Thanks,
Bill

Thanks again!

- Yes, separately.
- I was thinking, that my coin (could possibly???) was
punched with the die after the "re-alignment to correct".

Thanks again,
J

You need to study how dies are made then all this becomes much clearer. You are , as we say, mixing apples and oranges.

Some of your questions are difficult to answer because the questions themselves can't be fit into know segments of the minting process.

There is a tendency to confuse what happens with a hub, what happens with a die and what happens when a coin is struck.

Go to this page at the Mint's website. Click where it says "HOW CIRCULATING COINS ARE MADE" after you click on the link in this message. It will help you to see how coins are made and that will answer many of your questions.

Thanks again!

- Pls refer to the Thread of "1988 Transitional Reverse
Cent" referring to a certain Die Variety Magazine.
Just saw a cover story on DDO on 2004 Roosevelt Dime
(by Bill Crawford) due to this die correction.

Thanks,

Once on a die, the designed transfered to each coin will be in the exact same position. Machine doubling, since it is created from the coin bouncing into the retreating die, is a co-incidental occurrence and will not remain constant. While some machine doubling does at times appear to be similar, small deviations will be seen as far as design elements affected and strength of the doubling.

If machine doubling were a constant and could be associated to a particular die, then the number of coins affected could be known. This would equate to a value based on population of that number of coins. Since machine doubling is random, values can not be assigned. Therefore, with the value unknown, the collectibilty of this type anomaly is low key (not many people will collect something with an unknown value base).

There are instances (which at times leave me bewildered) where machine doubling coins attain a very high premium (example; the 1969-S Lincoln cent). However, I do believe that such high prices are linked to people who do not know what they are buying or believe that it is something that it isn't.

If you like machine doubling coins, then by all means collect them. I do have some extreme examples in my collecting. The important part is being able to differentiate between true doubled die and a machine doubling coin.

Someone once said that any sign of doubling on a coin will have a less than a 1 % chance of being doubled die; that was during the multiple hubbing era.. In recent time, with the era of the single squeeze hubbing, that percentage may have increased a bit, but it is still very low. The vast majority of coins that show doubling are either die deteriorated or machine doubling; it is a simple fact.

You are entirely missing what we are saying.

Doubled dies do exist on more recent coins. Wavysteps explained how in his thread. What you are trying to do is relate todays doubled dies to the many ways they were created prior to single squeeze technology.

That is where you are mixing things up completely and drawing incorrect conclusions.

All the information in this thread and others as well as the info on the mint's website is really all you need to figure this out.

I know that I can't explain it any further. Its all in the threads, you just need to read it several times to see what we are saying.

Thanks,

There is no such thing as a "die correction". I can't imagine what you're referring to. I strongly encourage you to get some basic references on minting errors, die varieties, and the minting process. For varieties, buy the Cherrypickers' Guide (4th ed). For errors, buy The Error Coin Encyclopedia by Margolis and Weinberg or Minting Errors and Varieties by Alan Herbert.
