O.K. Thanks for the info. The Maple leaf is 24K then.
Still out on the .999 and .9999 as being the same though.
The spot price of gold is actually based on 22K. .999 silver rounds actually have some copper/zinc. in them for extra hardness to produce them as coins but are marked as .999
Did not realize that the fineness numbers on gold and silver
Okay... a while ago, the best processes to refine gold could only do so to one part in a thousand. In other words, if you had a thousand granules of sugar, one of them would be a flyspeck and you would have 999/1000 pure sugar... your sugar would be .999 fine.
Now, with modern technology being what it is, we can refine to .9999 fine... if sugar, only one flyspeck in ten thousand. Or even .99999 fine... one flyspeck in one hundred thousand.
Back to gold... ALL of these designations .999 , .9999 , .99999 refer to pure gold. 24 karat pure, or 24 parts out of 24 parts. Typically, you will never see 23 47/48ths (<read twenty three and fourty seven fourty eigths) or some such other bizarre fraction karat gold... the 24 karat deignation being old and entrenched as pure gold.
So, refining gold to purer and purer specs is a technology where the method to measure/quantify the purity must also keep pace with refining.
Spot gold price IS based on pure gold... 24 karat... .999 fine or better
... better being more nines purity.
When we are getting to all these nines fine, some infitesimal, real tiny amount of dirt
is in the gold... but the reality is, that for any purpose it is considered pure gold... 24kt.
Same for silver... .999 fine would only allow for one one thousandth of some impurity... impurity, not a hardener. One one thousanth of anything would not alloy as a hardener.
Fineness for gold and silver is quantitatively the same for both gold and silver. So, one troy ounce of .999 fine silver will weigh one troy ounce. One troy ounce of gold(or silver) at .999, .9999,or .99999 fine will weigh one troy ounce.
22kt gold is 22 parts out of 24 parts pure gold, or 22 divided by 24 to get the ratio of gold by weight... which is .917 fine... 91.7% pure, so multiply the total weight by 91.7 to get the pure gold weight of a 22kt gold item.
