Hello all can someone help identify my cool old button and this super worn coin? The coin is 32mm diameter made of copper I believe with some good weight to it.
any help would be great thank you!
Have you tried soaking the coin in mineral oil and gently scratching the surface corrosion off with a toothpick? Looks like its thick enough that you can still get some detail out of it. I'm not seeing any markings though.
