New Quiz. Marks on coins.

Thanks for telling us that the marks of interest are into the surface and not raised.
That would be helpful to know from the first post; I don't know about others here but I have a hard time telling raised from incuse marks from 2d photos.
The marks on the cheek look regular but interrupted, not like the long lines from rollers. I'm thinking some kind of coin counting machine?

Sawdust. Is this an 83-O, 84-O, or 85-O? These sorts of marks are quite common on these three dates. There's no metal movement that you would see with bag marks.

 

In his original version of the OP, he said all of this, but then he edited everything away except the pic. Not a very helpful way to do a quiz, if you ask me, and it's what really bothers me about this guy...nothing but disorganized crap.

 

To be honest, I think he got pissed at Chris and me.

 

Snowflake.

 

I'm just kidding of course, but he is a disorganized mess if you ask me and I am purposefully trying to do my part to change him for the better

 

Could be lint from a polishing cloth left on the die too

In this case it is PROBABLY sawdust because up until the beginning of the Twentieth Century planchets were dried in sawdust.] But I am more wanting to know something. When you are in that seat and you are evaluating my coin. What power magnification are you using?"

I answered this somewhere already. I'll look for the long version and paste it in this thread if found. Short answer:

1. EYE and 100W incandescent.
2. 7x and 100W incandescent.
3. 7X Stereoscope and florescent.
4. Sometimes back to 7x and incandescent.

Remember, I'm looking for every defect* to take pressure/time off our professional graders.

All SE skip #2 and never get #4.

Edge hits, edge file, repairs, altered surfaces, damage, hidden scratches, counterfeits, etc.

Goodbye #3 , you lost your chance and "flunked out."

Just give us your answer already. Per your poll, this is another problem I have with these things. This one has been going on for 4 days and 4 pages filled with largely blah blah blah, and by the time you give an answer I couldn't care less. Set a time limit like 24-48 hours and then give a clear, concise answer.

 

Sorry, I get busy. Note that one of the marks on the coin has already been answered.

As for the other set...the parallel dashes on the chin. I DON'T KNOW WHAT CAUSED THEM!

Here is what we know. They are into the surface and uniform. They are in a flat plain and are fairly common if you look at enough coins - especially dollars. They can be on the relief as in this case or in the field. They are not PMD! They have the same color inside the mark as a struck thru SO THEY WERE ON THE PLANCHET and not struck out when the coin was made. Therefore, they are planchet defects of some kind.

As to what caused them? The only thing I can think of is something to do with the rollers. Any more ideas? @Lehigh96, @messydesk? John Roberts?

 

Can some one point to the post where this is?

 

It was? I must have missed it. Where was it answered?

 

He's like an idiot savant with a box of crayons and ADD.

 

Come on man. You post a quiz and make a big deal of it and have no idea what caused it yourself? That's not a quiz. That's an exercise in frustration for everyone who's hoping to learn something here. You know I'm one of your biggest fans and defenders, but this is just whack.

I realize that you don't have full pics of the coin... but do you perhaps have other examples of the same issue?

Or, does someone else besides Insider have pics of the same phenomenon? (preferably with a full coin shot)

What pushed you towards a strike through or planchet defect instead of some very old damage that has toned over similar to the rest of the coin?

 

Well, there you have it, my problem in a nutshell. I don't even know what we're talking about anymore.

 

What makes the most sense to me is some debris imbedded in the rollers used to flatten the metal strips.

Yes, exactly.
