1964 D Jefferson Nickel RPM

[TheNickelGuy]

My first post. Not sure if this is a D/D/D or a D over D but I see three distinct plateaus. Have not found this particular one on Variety Vista and thought it might be of interest. It might be there and I missed it, or might be shown elsewhere but I am interested in seeing better images of the same than I can take.
Thanks for your thoughts.

Greetings and congratulations on making your first post, now I only see 1 D/D/D if this is to be that one I would go away from the mint mark for now and ask if you can take two photos that are clear and please not supper close but close of 1) the letters LIB in Liberty that will have the field under them visible enough to see if there are the three Die Scratches under the "L"2) to the left of the Monticello and North to see if Die Scratch are there.
The photo you provided is a bit over lit and is distorting the details that`s needed to see to asses for a RPM. Well I`ll cross my figures and wait for more photos as well to see what others think.

Thank you for your attention to my post Dutch-Tigger
Hope these will suffice. Spent an hour on trying with a cheap microscope I have. I think it's an improvement, I don't think I can do better?

Hope there aren't too many pictures.

almost thought for a second it may have been the 501 but this coin mm is too far west, hanging over the step below.

w/o better pics, i'm going with standard md.

the pics aren't too bad but just not umm, i guess clear/bright enough?

[TheNickelGuy]

I thank you for your thoughts on this occnumis2021. I am going to add this wider image. I think machine or mechanical doubling (MD) would be apparent on other lettering which I do not see here.

that is usually the case i concede but i've seen plenty a mint mark with m/d but not on other devices. washington quarters come to mind first. but have seen it on lincolns, jeffies, roosies, frankies, walkers etc.

thanks for better image but after tinkering with it, i'm still in the md camp but there are a couple spots marked by arrows that COULD possibly indicate rpm but i'd be a new one i think.

the biggest problem is that rpm and md can be there simultaneously with rpm, ddo etc. ugh

also, please remember, we can only do so much with images that aren't professional and that we haven't seen the coin in-hand.

I will concur with OCC , the presence of an RPM may be likely but with the added MD to increase the number of steps. I also do not see with these photos the Die markers under LIB . Without a coin in hand with this state of condition on the MM its difficult unless higher quality and real high quality photos can be taken, it may be time to consider some better optical equipment to aid in this.

The photo's look OK to me, I'm sorry nickel guy. I don't see an RPM anywhere. What you are pointing to to the south to me looks like MD. Nickels are terrible to attribute. The other photo's look LEDS and I just don't see anything I would feel confortable calling an RPM.
P.S. that to me looks like Localized MD to re interate.

Yes, I agree with Eric. In my opinion, look at the width of that lower horizontal part of the D, it is like one third the width it should be.
One has to remember that the working dies had the mint mark hammer into them, so when the planchet is squashed into a coin, all it takes in a slight strange ejection and things like machine doubling can be present. If the mintmark was hammered into the working die at a slight angle, that can add to issues as well. In any event, it's some sort of worthless doubling.

Well, I thank you all, even though I am a little disappointed that I didn't find a RPM.

Hey Guy, I couldn't stop thinking about this to have a more in depth understanding, so from time to time between forum duties lol, I found an interesting description that seems to appropriate here.
Two actions may have caused this phenomena; a chattering anvil die or a resonating coin.

Like any solid material, a coin will vibrate or resonate at a certain frequency when struck. In that very brief moment that the coin does come into the second contact with a die, the vibrations generated by the coin will cause the multiple steps of machine doubling to occur with just one contact of the coin to the die.
Just more to think about, I do really like the look at this specimen you have. So maybe a new acronym needed "VMD" Vibration Mechanical Doubling ?

HEY neat-o

didn't remember seeing that final post to this thread originally. so worthy of a TTT.
