While I "Kind of Agree" I have a single issue.
The silver area is larger than the copper under it. The scratches on the base are from me trying to scrape the glue that was holding onto a card.
The copper core is a smaller diameter and has no tooling that I can see under a loop. To mill this, you need to secure it to something, and that would leave marks I would think somewhere. The copper core being smaller that the top is an issue as well.
Now I also think something is not right, but the How and the Why is where I am at.
