What is the Difference Between a 999 and 999.9 Silver Bar?

The difference between a 999 and a 999.9 silver bar is negligible. Both are considered investment-grade and are essentially pure silver with only a tiny fraction of impurities. The only difference between the two is in their purity levels. .999 silver is “fine silver,” while .9999 silver is regarded as ultra-fine. The difference in purity is so minimal that it is hard to notice a visual difference between them.


Here are some key points to note:


  • When silver is refined and melted down, any impurities in the silver rise to the top to be skimmed off.


  • 999.9 is the same as 9999, and both are considered pure silver.- Fine silver is softer than other silver alternatives and could dent much more easily.


  • The markings to look for in the United States include ".999", "999", and ".999FS".


  • Fine silver bullion items can be quite valuable, and there are a lot of fakes on the market, so it's important to know how to properly identify fake silver.



In conclusion, 999 and 999.9 silver bars are essentially the same, with only a tiny fraction of difference in purity. The difference is so slight that it is hard to notice a visual difference between them. When buying silver bullion, it is important to be aware of the markings to look for and to be cautious of fakes on the market.
