And the numbering strikes me as a bit odd since there are 4 placeholders (which implies =>1000 bars) but there are only 1-100 bars.
Anyway, I hope all goes as planned for you. I definitely like the look of the back of the bar.
They used to do this kind of stuff on eBay a lot back in the day. They called it "3 Mils .999 pure silver". They made it appear as if the mint name was "3 mils", but what they were really doing was giving you legal disclosure you were buying 3 mils of .999 silver xD
Its just clad, fake, not real.. Same with german silver its a combination of different material yes it is real .999 GERMAN silver, but not .999 silver..
