What's the difference of 999 and .9995 Silver? Am referring to OPM bars btw. http://www.opm-llc.com/public_html/1oz_green_silver_bar.html
Well you're sold 1 troy ounce of silver in either bar, so you will simply have a slightly lighter bar in the 9995, due to having less copper impurities.
Arent most .999 bullion coins slightly overweight? This would presumably offset the bees dick of missing silver involved here. More 9s dont make them 9 times as pure, and imo bugger all times more valuable.
This is what's first came to mind when I read this thread title. http://x-files.wikia.com/wiki/Purity
Could be wrong, I was under the impression it was determined by whom the bar was cast, only government sanctioned Mints can claim 99.9999 others 99.9995. Clarification or opinions??
Nothing at all. Investment grade silver is 999, Any number afterwards means nothing. You only have to be concerned if it's less than .999
*Nods In Agreement* I "think" even Maples weigh (ever so slightly) less than ASE's & often generics weigh even more again! .999 doesn't always mean the coins, bars or rounds are exactly.999 pure, rather their minimum purity is 99.9%. I actually "Nitric Tested" some generics vs some crappy maples i had and found that many generics to come out a deeper shade of red (indicating higher purity). Imho: When push comes to shove, if you need to liquidate in a hurry, as long as its .999 (or more) weight will trump purity every time!
all this talk about adjustments in weight sounds a bit off - and i'm just making it up as i go, but i suspect that a troy ounce of 999 or a troy ounce of 925 weighs one troy ounce. even 925 may be weighed and sold as bullion in it's own right. just that it is 925 silver rather than 999 silver. an exception i've come across is older mexican onzas which are .925 or sterling. onza itself means an ounce, and it contains a troy ounce of 999. a troy ounce of 999 is 31.10 grams, and for the coin to actually contain a troy ounce of 999, it has to weigh more - and the mexican onzas do weigh more at 33.625 grams. that's just stats - but the multiplication, 0.925 pure x 33.515 grams = 31.10 pure grams. the new liberdads, on the other hand, are minted at 999 and weigh 31.10 grams each. while i'm talking about liberdads - the coins that were produced between those older (beautiful) sterling onzas and the new liberdads are these pictured, which i think are the most beautiful coins anywhere plus, if you have the opportunity to handle them, their specs are perfect, they feel more perfect than any coin i've handled. but don't take my word for it.
