Sorry everbody, still trying to get pics. But can't someone just explain how MD happens at the bottom of the denomination and left side of cols 1-3, but not show in between? Like through the bottom left of the memorial base and planter area? Wouldn't that part double as well?

 

The key word with mechanical, machine, ejection, strike

The key word with mechanical, machine, ejection, strike doubling is random, random, random - sence it's a malfunction (of the striking process) it can and does effect one leter, one part of a letter, one end of a letter, one edge of a letter, one side of a letter, and on and on and on.
If you learn how dies or made and you learn how coins are struck you will then understand.

 

my 2 cents

Great photo!!!!!!!:kewl:

 

Thank you bhp, that makes a little more sense. I will study up on the die process. I really am trying to learn. There is so much more to coin collecting than just finding a decent one, sticking it in an album and sealing it with your thumbprint like I did as a kid!

 

Your welcome and don't get overwhelmed, all you got to do is

Your welcome and don't get overwhelmed, all you got to do is study 30 to 40 hours a week for thirty or forty years and you then know about 20% of what there is to know about US coins.
But like I always say, "where's the fire" right?
Seriously, you could easily spend a life time on one series and not know it all. But where else you gonna have this much fun?

 

Dude, I just bookmarked this page! My brother is always trying to bring over coins to show me and most of the time they fall in this Machine Doubling area. I fight with him all the time. Do you have a page dealing with other denominations?

 

At some point I may expand and show other denominations - I am not sure I have enough examples on hand though. I only recently thought this whole idea up of documenting and trying to understand MD so I am still trying to round 'em up. Also, the clad coinage would be tough as the DDD is rampant...

 

That is why I ask, because dealing with coins other than pennies is hard unless you are versed. I want to be versed Also, this is my 900th post

EVERY ONE SAY HUH UHH HUHUHH!!!

 

Congrats!

 

Yes, thank you jcuve. I have bookmarked the site as well and am reading your tutorials. They are very well done, informative and generous of you. That must have been a lot of work! It should be linked to the sticky at the top of the forum in place of one of the broken links.

 

Good going

 

Appears flat so I would say MD

 

You really do not need another site for other denomenations if

You really do not need another site for other denomenations if you learn how it (mechanical, strike doubling) happens in the first place.
It's the same reasons for all coinage.

 

Hi,

The coin exhibits machine doubling in spots and it also exhibits doubling that is associated with die deterioration (fancy name for die wear) Die deterioration doubling often effects the outer portions of design elements as those elements near a coin's rim.

There can be a combination of "worthless doubling" on the same coin and that can complicate matters.

Thanks,
Bill

 

True, but dealing with nickels and quarters for instance, there is a fine line I have seen that I still need help with. Pennies are much easier for me, because I deal with them 90 percent of the time, but dealing with nickels, for instance you have the Orange peel effect(just 1 example) and other parts to it that make spotting doubled dies harder. I am not talking about the major varieties either. I look for minor examples all the time and those are the harder ones to spot for me. I guess it just take more experience. I am working on it.

 

I think jessash1976 has a point, minor varieties that exhibit die wear (especially strong wear) are harder to discern than if the wear was not present.

If anyone has minor Doubled Dies or RPMs on nickels or on clad coins that I could borrow to photograph, PM me. I would be interested in shooting some, specially if they were MDS to LDS as the die wear would impact the identification of the variety.

 

Sorry everyone - still struggling to get pics up. Convinced of the MD obviously, I just want to get them up to possibly help someone else. I have learned so much from this thread - thank you all. Now, I'm off to my next dumb question...
