Answered, Thanks! 1 OZ .999 100 MILS SILVER LAYERED BAR How is this different from a full silver bar?
Something not brought out in that link. Yes a mil is a thousandth of an inch, but the manufacturers of many of the products such as the fake proof CC dollars and the silver plated WTC commems or the "Tribute" double eagles etc have been using the term Mil as being short for a MILLIONTH of an inch so a 100 mil plating is only 1/10,000 of an inch thick or about half the thickness of the copper plating on the current one cent piece. I knew something was wrong because if it was a thousandth of an inch many of these 100 mill plated pieces would be thicker than they actually are in real life. 100 mils is a tenth of an inch, and hat plating is on both sides! so that would mean 2/10th of and inch thickness of silver on a piece that is less than 2/10th of an inch in total thickness. That's when I did some investigating and found that the companies were usuing it as an abbreviation for Millionth.
I doubt in reality it's even a millionth of an inch. Most platers selling this type of stuff plate in microns, many being just 1 micron, or 1 atomic molecule's worth of plating. If you were to be able to scrape it all off, you'd barely be able to see it with the naked eye. Guy~
At the risk of being pedantic and distracting attention from the point you were making, an atom is way smaller than a micron.
True. An atom is about 1/10,000 the size of a micron. But most plating is fractions of a micron. So small it's almost not even there. Guy~
The diameter of an item of neutral silver is around 300 picometers depending on who you ask. If I can get a decimal point correct, .0003 microns.[/nerd] Getting back to the point you made, it turns out that there are places which plate on even less than a micron, in which case it's really stretching a point to use the word "silver" at all.
