If it comes off the coin with running water it is lint. Otherwise it is a die break. Now, as for doubled die coins...most actual doubled die coins that need high magnification to see are not worth getting excited about. You would possibly have better luck buying a bunch of cent rolls and looking at the coins at 4-5 power. Then if something is a genuine DD with NOTICEABLE SPREAD, you'll possibly have something worth your time. Nevertheless, don't get discouraged or let me dampen your enthusiasm. What ever is fun for you works.
It did not come off with water. Wexler does show some doubling on the beard. I just can't tell though.
I'm talking about the vertical white line in the photo. the MICRO Doubling you are looking for usually cannot be seen in a photo. That is one reason I do not join your posts anymore.
The bottom of the beard is MD. Look closely it's flat. It's common on 1960's cents but I've seen that on 1950's, 1980's, and 1990's Lincolns as well.
I know, I see nothing there except "glare". Rotate the coin in the light. Now what about the vertical white line? Just curious.
It Looks more like a die crack. Slightly raised. The one on the bottom of the chin is Raised and rounded. I was kind of thinking Maybe machine doubling.
Sheila, I am not yelling at you , I use caps as emphasis: Let me be more specific. Yes, it looks like a die crack. Perhaps it ONLY looks like a WHITE PIECE OF LINT that is turned up at the base because of the direction the light is hitting it. Put the coin under running water PLEASE. Now, the only indication TO ME (and it is a good indication) that the vertical white line MAY BE A DIE CRACK is the fact that it is raised at the top and bottom of the photo and very weak on the cheek - so it may be worn there. I still think it is lint.
Cool! Now rotate the coin and take another photo OR if the line is raised it is a die break and a neat one. Lucky You. One more thought. Put some nail polish remover on the neck, just to make sure. You are in the best position to see if the line is raised from the surface.
It is raised from the top of the bowtie to the top of his head. Definitely. I don't know if this helps.
