I was wondering what causes this to happen? I have seen it a few times and was hoping to know how this happens so when I see it next time I will know...
It's a 'woody'. Improperly mixed alloy make the coin look like it has a wood grain. I don't know if these have a premium, but someone that will know will be around soon.
Thank You, not sure about the premium either but it sounds neat to talk about. Thank you again for the info.
