1982 Plain Zinc Large Date DDO DDR?

[mikes7657]

I hope that what I said about the experts was not percieved as being sarcastic. I hold a degree in math, and a .01 % statistic is not something I normally chase after. I joined these boards so I could learn from what I see, what I've read, and what I've seen that the experts say are DD coins.


If I feel strongly enough about it, like you did, I will do exactly what you did. There is nothing wrong with that. It's a part of the learning process as well.


I am 99.9 % sure this coin is as they say. I am most likely wrong about the doubling in some of the characters. One lesson already drilled into my head from reading that bugs me is that the machine is usually more consistent about the doubling, it is usually of the same class. I am puzzled by that with this coin and will continue to do research and learn.


If I still feel the same after more research, I'll do exactly what you did. It will cost me all of 3 dollars and some postage to find out. I doubt if I will ever have to do that. More research usually takes me into agreement with the experts.

Mike,
Nice to have another math geek on the board. One of my degrees is in mathematics as well. As for the doubling, I am unclear what you are saying about the machine being "more consistent about the doubling." More consistent than what? Are you saying that machine doubling is more consistent in the way it shows on a coin compared to a doubled die? Can you expound on that for me please? Also, what do you mean when you say that the machine doubling is "of the same class?" There are no defined classes of MD that I am aware of, although it can sometimes be quite severe. Here is an example of slide MD on his head.
Anyway, if you can clarify what you mean, I could try to help you more.

Here is my tutorial on MD: LINK
It might help.

I found out where I went wrong. These images clear it up. You folks have no idea how much I appreciate all of the help I'm getting here. I've learned more in the last three days trying to figure out where I went wrong than I have from weeks of reading.

I was fooled into thinking I was seeing notches and splits on some of the lettering, and it is cleared up by some of these photos. The angled date photo is a dead giveaway that the machine is up to it's tricks into fooling the novice into thinking splits in the 9 and 1. I don't need to carry on, you can see how I was tricked by the photos.

Glad to see you are figuring it all out Mike. Keep up the hunt. With vigilance and a few thousand coins searched you might find a variety or two lurking. Nice new photos BTW.

I mean the machine is more consistent in the way it shows on the coin as compared to the double die. Additionally, I mean how the machine doubles as compared to the classes of hub doubling. I am having a hard time figuring out how a machine could do a distorted hub doubling.

My English is not too great, sometimes.
