1974 S 50c RPM

Good Friday morning to everyone. I can't remember when I had picked this Kennedy up but was looking at it when the MM caught my attention. I looked at it from all 4 directions and even angled to make sure it was raised and not a reflection. It looks legit but needed everyone's opinion if it is an RPM. The 3rd pic is taken with a loop while pics 4,5 AND 6 are under a scope. I can take and post more if needed.
Thanks

I think it's just a shadow/reflection nice coin though.

 

how is that a reflection? Nothing else is reflected. Looks interesting. I'll wait for further opinions.

 

My first thought--

but, I would think about it, I'd like to see it in person, perhaps bite the bullet and send to PCGS?

But-- it could be a reeflection.\

 

It doesn't look like its actually struck into the coin,besides that could it be ghosting?or a droped letter?

 

Ghosting appears on the opposite side of the coin... Basically a die clash, but without sharp edges and it looks like a "ghost" image. See here.


Possibility of a dropped letter still stands though.

 

I took these at about a 30 degree angle from all four directions thinking if seen from all four it would eliminate a reflection I hope. Oh and thanks for the quick responses.

 

I'm leaning into droped letter but we need a specialist to chime in. @paddyman98 what say you?

 

Proof coins are double struck, further accentuating detail.
This is not an RPM, just a proof coin

 

oh i see what youre talking about now

 

You need to take it out of the 2x2 and shoot your images. Quite often, the mylar reflects the image just like a plastic case would. If the secondary "S" still shows, then it is an RPM.

In my opinion, it is just a reflection. Note in your last set of photos (Post #7) that the secondary image is further from the normal mintmark in #1 & #4 but closer to the mintmark in #2 & #3. It should be the same distance from the mintmark in all of these images. The fact that it isn't is because you are changing the angle of view which also changes the angle of the reflection.

 

My first impression is that the coin impressed the device and date images onto the plastic of the 2 X 2 and then moved. I see the number 7 also duplicate to the right of it.

 

...and be sure to post a pic of the mint mark out of the flip. It appears to be an impaired proof...imo...Spark

 

Have a read of this - Flat Field Doubling (error-ref.com)

 

Interesting never heard of it until now.

 

Sorry, I'm not a specialist .

 

I read that, but it wouldn't explain how far the shift would be on this coin, and i just see it on the MM.

 

The 1960-D Cent has a funny RPM well-separated like this. I'm thinking this could be an RPM.

 

@Evan Saltis I had the same thought...but what lurks back in my mind is an example I saw some time ago. What helped trigger my thinking was the comment you made earlier; proofs are struck multiple times. Yet the separation is extreme.

No known RPMs for the date, so while possible, probably not likely. But it sure does look like one. Almost like an impression on the plastic of the flip being reflected.

 

Anyone else notice that the primary MM appears to be MMS-001 and the secondary marks appear to be MMS-002?
