Well done! These look beautiful.
So the only numbering is on the COAs?
Thanks for the kind words!
The numbering is on the COA, and we'll be updating the website so that scanning the coin's QR code or visiting it's webpage shows the production number as well.
I would love to see numbers on the actual coins some day. The CoA are nice and all, but they are just an extra something to keep track of.
Edit: Or even just printed onto the holograms
