What “.999 fine” on a bar actually guarantees (and what it doesn’t)

The stamp is the refiner saying 99.9% pure. It is not a police escort. We still weigh it, measure it, and sometimes look at the middle.

.999 means the refiner claims 99.9% pure.

If that refiner is a name we see every week, and the bar weighs and measures right, the visit is short. If the stamp is a brand we have never heard of, or the corners look poured in a garage, the stamp is just ink.

What it does not guarantee

That the middle matches the skin. Tungsten. That we will pay Eagle money for a no-name bar. Government vs generic. That an extra nine on .9999 is worth a fat premium. Fineness.

What we still do

Weigh. Measure. Sometimes XRF. Sometimes a second test. Tests. Hallmarks. Kilo bars.

If you like pretty stamps, fine. If you like sleep, buy names a shop will still recognize when you are not in the room to explain them. How to tell if a shop is legit.
