銀幣999和9999的分別

銀幣有分999和9999純度, 而9999是純過999, 因為加入其他金屬(多數是黃銅)少些 ! 所以9999銀幣會比較軟好易花 !

剛睇到在Kitco forum 有人說 9999銀是多數用在高科支工業上, 但一盎司的銀幣, 就算999或9999都是得31.1克的純銀 ! 有些銀幣會重好多, 因為加咗好多其他金屬 !

銀幣都有低過999的, 如925(sterling silver), 900, 720等等, 所以你要查清楚, 你手上的銀幣實在有幾多克的純銀 !

One dealer at a coin show said .9999 was softer & scratched easier than .999, who knows though.Well, the 0.9999 is 9/10,000th more pure than 0.999.
The silver content of either is usually the same (1 toz, 1/2 toz, etc...).

Some (very few) manufactured high-tech goodies benefit from using the 0.9999 as stock over the 0.999.

9999 silver is industrial grade silver
anything less than four 9`s is only investment bullion.
