.999 Vs .9999 Purity 


SilverMine

Recommended Posts

Hi all,

As I am fairly new to Silver, I just wondered your thoughts on .999 vs .9999 purity.

Looking into this, it seems that both count as pure silver. But I wanted to check if I am actually missing a trick by not focusing on .9999? Does .0009 actually make much of a difference to future value and quality?

Sorry if this appears to be a daft question to those of you with lots of PM experience. 

Thanks,

SM

If silver went to the moon would a Maple be worth $9999 whilst a Britannia is only worth $9990   ?

That would be a nice problem to have.

Yeah, would you love to gain 9$ with a spotted coin, or lose 9$ with a nice shiny one?

Me personally I don't deal with these impurities, only focusing on .99999 silver.

.9999 is ten times as pure as .999.

 

Mathematically. But in reality, it makes not a jot of difference. The daily variation in spot price is a larger order of magnitude than any value difference in silver content.

Is it not .0009 times purer? 

To me it makes no different either, it seems that extra 9 improves our chances of getting milk spots, nature doesn't seem to like perfection.

No. It is 0.0009 purer, on a scale of 0 - 1.0. It has a tenth of the impurities of .999 silver, so one might say it is ten times as pure.

 

But I was pointing out the meaninglessness of this.

.999 is 999 parts per 1000 therefore 1 part per 1000 of impurity.

.9999 is 9999 parts per 10,000 therefore 1 part per 10,000 of impurity or 0.1 parts per 1000

therefore it contains 10 times less impurity but that is not the same as 10 times as pure.

To be 10x as pure would require one coin to be 10% silver as opposed to 100%

They are both virtually 100% silver, the difference is negligible.
