@boj, with coins minted in the US, we occasionally see them struck through a bit of foil — https://www.error-ref.com/?s=foil. Do you suppose that something similar happened here? If this coin was Struck Through Grease, then those areas would be incuse rather than raised off the surface of the coin. "If you climb a good tree, you get a push."

The places in question are not deposits of glue or some other foreign body. The raised surface of irregular shapes is metal (the material of the coin from which it is made). Very interesting.

Is the following scenario possible? That it is a place that could have oxidized on the working surface of the die, or that it is a broken surface layer of the die that was cemented and not adequately tarnished. I know from experience that cemented steel splits, that is, separates like slag from red-hot iron during forging. I have a few more pieces in my collection with very similar appearances on them, I will definitely look for them to display them. Maybe we will come to a possible conclusion about what happened.

Sorry, but it's almost certainly glue. Some forms of glue are transparent (like epoxy resin or "superglue"), and as such it often looks the exact same colour as the underlying metal. Whenever you see a "raised lump of metal" on a coin and it has a clear, obvious "coastline" all the way around it like this, it's almost always because the cause was indeed liquid - a blob of glue (or in this case, several blobs of glue) rather than some weird die damage. You would be surprised at how many times someone comes on to the forum and they are absolutely certain that the weird lumps on their coin are not glue but must be metal, and it turns out that it was actually glue all along. I'd recommend soaking it in acetone. Not all "glue" will dissolve in acetone, but most of the transparent ones will. That's a simple test you can do. If it were genuinely some kind of weird mint error, a soak in acetone won't hurt it - but just might reveal that it is indeed glue.

I tried again with acetone, and some other substances that I know will react to the glue, unfortunately the glue is not in question. As unreal as it may seem, this is the material the coin is made of. The only logical conclusion I can make is that the die was damaged by one of the ideas mentioned above. of course, I added lubricants in the title because my first thought was that the die had hit deposits of dust, dirt, lubricants. and the pattern remained imprinted in it, which is why this is the final product.

How long did you let it soak in acetone? You may need to seal it in a glass jar and let it soak for a week or longer. I trust Sap's opinion, but I also need to give your senses some consideration since you have the coin in hand. Definitely keep this coin. Set it aside for now because we may not be able to make a final determination any time soon. If you had not already done so, check out Spence's link above and do some searching from there. |

Great images of these. I see on the last image that the texture is the same as it is on the fields.

OK I found a good normal looking coin like the one up above. When looking at the OP's coin the date and ORE squares and the circle around the 1 looks incuse to me, and the and the '!' and the Crown appears raised. but the opposite is how this coin was struck. Going by this information (and the lighting) I say that these features are actually incuse below the fields not raised.   |

No, everything in this design is incuse - the crown, the date, the denomination, and the large central circle; the only thing that's in "normal" relief is the large "1" in the circle.
I still haven't seen any indication that this is anything other than some kind of glue-like liquid on the surface of the coin. The close-ups clearly show the liquid flowing down into the lower areas of the coin. I just can't see any way that a die can fail and generate this kind of liquid-like effect.
I would say the same for the Danish 10 ore.

Was the Swedish mint using chrome plated dies?

Very curious, Bojan. It could be grease errors - I don't have a better explanation.
