Hello,
I see you are making a few requests for mints. This is good, but we need to know a few things.
Do these companies mint their own bullion? or is it outsourced and they just package/label/retail it.
Then we need a rough address, otherwise, we cannot add it. Optionally, a short history (any relocation, founder, engravers, etc) and mintmark would be important.
I have contacted many mints directly to get this kind of info, see here an example:

But this is time-consuming and there is often no answer.
