What does .999 fine silver mean on a silver bar?
does it mean the bar is 99.9% silver?
It is virtually pure silver. It is impossible to get anything 100% pure (even the refining process leaves impurities!). Possibly the 9s are recurring so it's probably purer than 99.9%
I think it is 999 (three nines pure). The purist, apparently is 999.999% (Gold)
Exactly! Youve won the prize good sir!
