Machine Doubling Can Occur During The Strike

Here is an extreme example of Machine Doubling.

For something as pronounced as your quarter, to me it makes sense there is an attached value. I think it would be great to find something like this.

CoinMasters , I had not heard Die Deterioration Doubling being refered to as Machine Doubling before. Not too sure it should be. Though both types of doubling happen during the operation of the same machine, they are not that closely related .
Die Deterioration affects the die and produces coin after coin with the same characteristics. Machine Doubling is a one shot deal per coin.

The jest of my post is that while we've considered Strike Doubling to have occurred after the strike, it occurs during the strike. I personally have always felt that when the die releases the strike is over. Now with Mike's statement, I think that's acceptable.

Mr. Richard Cooper, you know you have my highest respect and gratitude. You sir are one of a handful of leading experts and have helped myself and many others understand the intricacies of our hobby, in my opinion, more than all the other experts put together.
There are as you say, two camps. Both are good camps, just two different schools of thought. One camp is the Purists, the everything is black and white traditionalists. To simplify, the Purists love the Gem BU Doubled Die, and tolerate the Prisoner Cent. The other camp loves the Gem BU Doubled Die and the Prisoner Cent. That's it plain and simple.
I understand your reservations about "To think more of MD as what it is get people on ebay to consider it more valuable" , because there are unscrupulous people on ebay. That is however not what the second camp is all about. The second camp genuinely appreciates some of the "unwanted mint errors". That's what gives them value, as affirmed by Mr. Mike Diamond himself.

Tunnioc, start yourself a thread with that one. A lot of people only read posts once. Post it and you'll get more responses.

To me the strike includes the first point of contact to the point contact is removed or released. Any motion in between is still part of it.

Just my thoughts. Thanks, Doug.

I wanted to follow up this topic of what I consider desirable and what is not to me. Take into account I currently don't buy or sale.

I'm in coops camp when it pertains to the minor MD's. Same with minor die cracks or Die Deterioration. Seems we see so many everyday. Though interesting examples abound, I can't think there is an actual collectors value for the more common examples and should not be exploited as valuable to the public.

Then there is the extreme examples of MD, also including large die cracks or severe DDD. We don't see everyday. I know I save them because they're unique, or like one of a kind. I believe these are collectable due to you're not finding another example anytime soon if ever.

So it boils down to supply and demand or its in the eye of the beholder. If someone is willing to pay (over face), then there is some value. I have no problem with that as long as the description is honest and or does not include any deceptions. Thanks, Doug.
