Hi all - its been a while since posting, but I ran across an odd mounted coin today which I haven't been able to push out of my head, and would love some input/advice, please. I came upon a 1904 22ct gold USA $20 coin today, with an Edwardian style mount. It was beautifully weighty in the hand. Tell me; how much would the mount affect value? The total weight is 41.9g. I have taken a handful of photos (the reverse tilted towards the light more), for reference. Can I please get any insights/comments/opinions on this one at all? Many thanks!
