So, die crack? Stain? Retained cud? Imho, I think we need better pictures with a white light and white paper background. To help give you a better determination. The background and tone in the pictures makes it difficult to determine.
A soak in acetone would probably also answer the question. After taking a second look I can see how it might be glue.
I’m not using a filter. Not sure why the coloration is this. Sometimes I do filter it to a more silver tone but it seems to distort the photo. Sorry ‘bout that.
Ok what do I need to do? Soak in acetone? How long? The photo was taken with a white paper plate for background. 2 gooseneck lamps over it. How can I improve it?
Soak it for about 5 min Imo the acetone will not hurt the coin. Then nudge the raised area with a rose thorn or toothpick. Don't ever get roudy with the thorn or toothpick. Then if it moves soak it till the raised area comes completely off the coin. If it is solid after 5 minutes then I would suspect it to be a die crack. Some glue is more stubborn than others.
I did not clean it until requested ( after the photos) and then just a quick brush with a soft toothbrush and Dawn detergent.
oh - idk dude - the reverse looks ok but not even the plate does in the obverse photos. White balance maybe?
@Chip Kirkpatrick - do you have florescent bulbs in the lights? That might be the problem - outside pics on the new thread look good.
light bulbs can have different "colors" Flourescent bulbs can flicker. LEDs can also be in different colors. If you ever see "Cool" color then it's a shade of blue. Versus others that can be more yellow cast. If you have different ones then it creates problems with the camera's white balance. If you have other surfaces of other colors around you can be getting color casting - light/color reflection. If you ever see ppl wearing some bright green shirt in a photo on a really bright day have green skin; that would be an example. https://www.cambridgeincolour.com/tutorials/white-balance.htm So you have to be aware of not just your white plate, which is good, but of the light bulbs, angle of light to the object and the immediate surrounding area.
@Clawcoins ...great info!...So, if this post #32 is after an acetone treatment, then the glue issue should be dispensed with...and a die crack appears to remain along with an associated retained cud, maybe. That's what I see. Not so sure that what I see is what I get. Anyone else want to chime in?...Spark
Top of the head is nothing but a stain As for the circular area, I think it is a solder job. It doesn't look like it left the mint that way. Cool collar clash though.
