this is the way it is listed in the UK . This one has the complete outline of the Queen's face and head.
What is your opinion of the kind of strike you think it is.

Machine doubled damage (MDD) also sometimes called strike doubling. Long ago it was called a "chatter strike".

 

Thank you for your opinion.
when I received this coin, of course what you have mentioned were the first things I thought of.
Then I asked myself this question have you ever seen this type of doubling before in some 80 years of collecting errors.
It is a good possibility that this old man has just not been looking in the right places. I know the photos are not the best quality, and I am fortunate to have a coin in hand.
But have you seen this type of doubling somewhere else in another coin please provide the link. Each type of doubling that you mention has their own distinctive markers to indicate the type of doubling that occurred, this particular portrait strike has none of those markers.
Believe me I have been looking and looking ever since I received this coins last year.
Again thank you for your opinion.

 

There have already been a couple posts today showing machine doubling. This is very common.

For a good explanation, please look at Wexler's site on worthless doubling. Also, take some time to read about die manufacturing. It's helpful information
http://www.doubleddie.com/1801.html

 

This is definitely machine doubling. You asked for markers? Shelflike doubling that reduces the size of the devices = Machine Doubling.

 

Thank you for your opinion and your advice.
Been there done that

 

You state boldly that it's definitely machine doubling.
The only thing I'm willing to say it's some kind of machine malfunction in the striking process.
If I may I would like to ask another question. What kind of malfunction would cause a portrait strike impression as you see in the coin.
I have provided another photo that shows the detail of the strike.
Please note the detail in the strike comes off the queen's nose down and back up nicely rounded back down to the face of the coin.
Yes I did mention markers one you have provided is a well-known marker for machine doubling. Unfortunately it does not apply to a portrait strike.

 

You said you read Wexler's Doubled Die site. Go back and reread the section on mechanical doubling that's listed in the Worthless Doubling tab. It explains the kind of malfunction that causes machine doubling. Then would you please explain why the characteristics of machine/mechanical doubling isn't applicable to the portrait?

 

Because it is. I've seen many coins with MD and clearly this is one.

Please, give me some information on why it 'does not apply.'

I completely agree with the above.

 

Machine doubling does apply to portraits. And the doubling in the close up does show flat shelf-like doubling.

 

All this merry-go-round is doing is making me want to puke.
Too old for this so let's start with coin number two.
This coin is similar to coin number one
2017 portrait strike again we have a nice raised and rounded not flat outside portrait strike now on the reverse you will find multiple die cracks in among the center design.

Let's try this again. What malfunction causes a portrait strike

 

No need to get sick over this, It's very straightforward. Did you take the time to read Wexler's explanation???

http://doubleddie.com/144822.html

He doesn't address Bimetallic coins but you can add to his explanation of loose Dies/equipment, a loose center of the planchet that can move and seat itself.

BTW: we DO NOT "have a nice raised and rounded not flat outside portrait strike..." It's flat. Classic example of mechanical doubling.

 

Like I said I want to get off this merry-go-round.
It is what it is. My suggestion to you and to the others if you can find one of these available purchase it for yourself.
After you have examined it come back on and we will finish the discussion.
I know last year there were quite a few of these available the average going price was between 15 and 30 US dollars. But it seems now everyone that Acquired one holding on to them.
I will have to say I find it kind of amusing that you and others who evidently have not examined one of these personally can come up with your conclusions.

 

After wasting money on a coin that clearly has Machine Doubling.

You find it amusing, I find it logical because I know that this is MD. This is also common on US coins such as Lincoln cents and Kennedy half dollars. Maybe not as noticeable, but definitely there. And yes, examining a coin like this in person won't change my opinion.

You can refuse to accept that it's MD, that's fine.

 

MD MD MD MD MD MD agreed no argument of this
there has to be a particular failure in the striking process to cause a portrait strike.
That's the only thing I'm trying to find out.
And like me none of you have a clue to what failure causes a partial strike

 

Okay, you provided pics for us to judge the coin by, then you fault those judgements because we don't have the coin in hand. You have gone, you say, to the Wexler site and didn't find the answer you wanted there. I say go ahead and get off this merry-go-round now and try selling the coin to someone who doesn't know as much as we do.

 

Partial strike? Portrait strike?

Let me explain what caused this doubling of the portrait. This type of doubling is created when the die strikes the planchet, which is unlike some other forms of doubling. If the die is slightly loose or not seated correctly, it can shift during striking to create the type of doubling present on the coin you showed. Note that the die itself does not have the doubling on it, unlike a DD. This type of doubling could be called a "defect" in the striking process.

 

Enough...just agree with the OP, he won't accept anything else. stop stop stop stop stop stop stop stop stop stop stop stop

 

Sorry, I know I look stupid doing this, but I am still trying to make it clear how this type of doubling happens during the striking process. Even if the OP disagrees, I am making it clear for future readers of this topic.

 

Be Best
