Proof or Uncirculated ? [opgelost]

I've got some Soviet Union rubles which have matte design and a brillant background as this Checkov ruble:

Are there Proof or just Uncirculated ?
In the Numista file, the proof coin appears with a blue background:

Thanks

That looks proof to me.

The "Blue" reflection is down to the photo being taken with something dark or black above it. Not the actual coin colour itself.

Thanks for your answer.
I would be happy to be able to take such a picture of coin

I'm pretty sure it's not a picture taken by a camera but an image of a scan. When I scan my proof coins you don't see the mirrorlike backgrounds but a dark or even bluish background.
Look for yourself and compare with the Russian coin:

Indeed that would also be correct. I have posted before how to take pics of proofs with a camera without getting your reflection in the image and instead have a black colour. You can have a colour reflection of your choice really.

It is quite a simple solution. (apologies for the blurry pictures, I have a nerve disorder and shake a lot)

How to remove this reflection



get a piece of black card larger than the width and length of the camera face (in my case a Samsung Galaxy zoom phone), the card has to be jet black as that is the only true colour that does not reflect light.



fold it in half and cut a tiny semi circle out of the centre so it leaves a small hole about 1-2cm when you unfold the card.



Hold the card flat against the camera lens and take the shot directly above, make sure no colour from the camera (in my case, hide the silver colour) is visible looking through the hole, only the lens itself should be visible through the hole.




(viewfinder will look like you are looking through a telescope/microscope), now you will have a perfect proof shot with no visible reflection. (camera held about 6 inches above coins)





now all you have to do is crop out the coin. B)

Wow, that's an amazing top Fluke! I'm gonna have to try it right away, haha!
Cheers mate, you may have change my world of coin photographing!

Good luck
I tried without success

This is how it turned out



I could probably add some light, but I'm very pleased with the result

Your Korean bi-metallic coin picture is very nice cause you get warm and cold colors

I understand it's a question of "balance of white" and "contrast"
