”Silver bars stamped .9999 or .9995 are no more pure than bars stamped .999, which is the industry standard.”
Perak yang dikatakan .9999 atau .9995 pada dasarnya tidak lebih murni dari yang dikatakan .999 atau ringkasnya; baik ditulis .9999 atau .9995 atau .999 hakikatnya sama saja.
“.999 fine 100-oz silver bars, usually stated as “three nines silver bars” have been industry standards since the early 1970s. And, they remain industry standards despite some refineries stamping higher purities on their bars.
For instance, the Royal Canadian Mint produces .9999 (“four nines silver bars”), and Ohio Precious Metals stamps .9995 on their bars (“three nines and a five”).
Meanwhile, Johnson Matthey, one of the most prestigious names in the precious metals industry, continues to stamp .999 on their bars, as does Academy Corporation. JM and Academy bars would probably assay much higher, but those two companies put simply .999 fine on their silver bars.”
Perak murni .999, terkadang juga disebut dengan .9999 sebagai standar yang sudah dilakukan sejak tahun 1970-an. Standar ini menyatakan baik .999 atau .9999 atau .9995 hanyalah stampel dari produsen saja dan pada dasarnya sama saja.
Sebagai contoh, Royal Canadian Mint menggunakan .9999 (“four nines silver bars”), sedangkan Ohio Precious Metals menggunakan .9995 pada perak mereka (“three nines and a five”).
Sementara itu, Johnson Matthey, salah satu nama yang terkenal di dunia industri logam mulia, tetap menggunakan stampel .999 untuk produksi perak mereka, sebagaimana Academy Corporation. JM dan perak Academy mungkin memiliki kemurnian lebih baik tapi tetap saja menulis stampel perak produksi mereka .999
Akan tetapi ada penerbit Dirham yang mengklaim dengan kemurnian .99999 extra-fine silver http://www.auruma.com/index.php/en/products-en/dirham-en/item/1world-10-dirham-coin
The Perth Mint achieved “arguably the purest of all gold” in 1957. Refinery Officer Leo Hickey and Senior Craftsman Alexander Osborne produced a proof ‘plate’ of almost six nines – 999.999 parts of gold per thousand – as measured by the Worshipful Company of Goldsmiths in London. http://www.perthmint.com.au/visit_the_mint_the_perth_mint_history.aspx
Ahmad I Adjie I know for a fact that 9999 silver is impossible, even the most pure gold bars come at 9995 (even though 9999 IS actually possible for gold) – the term ‘four nines’ is a marketing term for the bullion industry, of which, for example, you want to be listed in the London Bullion Market Association (LBMA), then all your bullion bar products whether silver or gold, must contain ‘fine gold/silver’ to the weight it says so on the certificate (or more) – this means that the ‘bar weight’, for point in discussion lets say a 100 gram gold bar – this bar MUST contain 100 gram’s worth of 9999 gold, even though it is assayed at 9998, so the bar itself must weigh slighlt more than 100. Does this confuse you? Not me. This is why to keep everything else equal (and for comparison’s sake), one of the advisories OMS has is that each gold/silver coin should state its weight in 9999 purity.A perfect example would be the Krugerrand and the Gold Eagle – both are 22k, yet both say 1 troy ounce – this is because the coins themselves weigh more than that, and that the fine gold content (the 9999 gold content) in that coin is 31.10348 grams or slightly more.The best way to ‘hike up’ the nines is by stamping and re-stamping (think katana sword), while the most trusted investment gold bars are cast (poured gold), thus 400 oz Metallor bars are never 9999’s. I would love to get my hands on a 12kg+ gold bar!Btw – more processing (and stamping) = more cost ; more cost = more premium ; more premium = less sharia
