2 Coins...machine Double Or DD? Opinion

The top looks like is a 1909P-1DO-001 would need to see whole coin.. as that's how you can tell on that coin the difference ....note that this is one the only coins besides maybe 1935P-1DO-001 that looks like that and is not Strike Doubling.

Which I assume is why you picked it...

but like the Strike Doubled which are very popular on the 1969-s, it will show flat doubling in varying locations, directions and strengths on the coin will look very simular..

These areas of doubling may be in similar or even the same locations as the genuine Doubled Die
But they do not show or have the well-rounded, overlapping, raised secondary images you see on the Doubled Die.

btw Stike Doubling is same as "mechanical doubling," " Machine Doubling damage," "shelf doubling," Etc..

the bottom like notice how "mushy" the doubling numbers are in appearance this is either a very late stage die with MD or Die Deterioration...but either way not a DDO

I still don't quite see it from the pictures they give.

Thanks!! Just went to coopercoins...bwahahahaha.
None the less, this is FUN...thx!!

John1,
I think we are on the same page, I'd said MDD to both even after looking at the Liberty. Nice to not feel alone in this matter.
I'll just keep throwing posts up and see what I learn. Just broke into 3 more 68 and 69 rolls...hope I'm not annoying anyone with too many posts. 😬

Note the difference between Machine Doubling and hub doubling. The hub doubling is enlarged/widened/taller. Machine Doubling reduces the size of the devices.

Coop,
(Cause I figured you'd look back at this post) what is your opinion of the layers on my 8 from my Edvard Munch the "scream" post? Is that Die wear? It's really layered with an even odder top to it. It has an effect like something melting. Curious. Not a double die or quadruple die? Just kidding 😊 I assume Machine Doubling with die wear, but why are the other characters not affected the same? I mean they are with layering but the 8 stands out alone. What do you think? Is it a one of a kind.?
BTW, I'm labeling my coins as: the scream, scare face, back side of the moon, etc...it'll be confusing when I eventually sell them off.


Extra red arrow is an error.

Note on your example the overall size looks altered? There was a slight amount of grease in the die when this coin was struck making the devices look wider and the angled bottom edge of the devices show machine damage on that area. If you look closer, you might even see metal striation on this lower edge. This happens when the die move making a lined area where this happens.

But your coin's die was normal, but with MD and grease it made the coin look different.

The 8 is also machine damage during the strike.

(Don't know for sure if these images are from the same coin, but it is best to use one coin per thread to avoid confusion and the thread title of the coin would make it easier to search.)
