No ,it's not hard to understand at all my main purpose of posting n this to warn my fellow collectors of a fraudulent piece floating on the bay.... and to help get the idea behind heres some more pics along Side a Mexican 5 onza Sent from my C6740N using Tapatalk
That's perfect. It's pretty clear from the photo that the fake piece is larger in BOTH diameter AND thickness than the Mexican piece. The weight in grams is always unambiguous; I wish we could all just go by grams instead of ounces. 144g is 5.08 standard ounces, well under 5 troy ounces. Thanks for clarifying, and thanks for helping to shut down one more seller of fakes on eBay.
"Perfect" would've been first page, first post.... Now, this begs the question of how does the OP know his Mexican piece is genuine without the need for holes or acid?
OK bigger and thicker would allow a silver plated coppernickel alloy to be used to fake it. By the way, just because two coins are different sizes in no way to judge if one is real or not. A silver eagle and anCanadian maple leaf are both 1 oz .999 fine silver, but they aren't the same size. A silver eagle and a one oz silver round are usually not the same size either. Same goes for real 5 oz silver coins. they are all the same weight, but they come in different sizes.
Uh..."Mass + density= wght"...not even close. Assuming wght = weight, then on earth for common use mass = weight. Density = Mass/Volume
The point conder is making is that measuring the diameter of twp coins and the width of the rim of two coins, and comparing them does not prove anything. Coins of the same weight and silver composition can have different rim to rim measurements based on the actual design depth used.
By the way, I have that exact same kitchen scale! but it sucks and I went to a gun shop and bought a scale that measures to 0.1 grains which I think was 0.006 grams. In much happier now.
But why is the larger coin weighting 5.5 oz larger then the Mexican version and united states 5oz Sent from my C6740N using Tapatalk
Just have to say, this does not quite convince me. 144 grams is 5.08 ounces, but it's been drilled and has lost some weight. The 5 ounce Mexican coin only shows up on his scale at 5.3 ounces, so his scale could be badly miscalibrated. These scales round, so that 5.3 could be 5.25 rounded up, and 5.25 ounces is 149 grams. So on the low side, the drilled coin could weigh 5 grams less than the Mexican 5 ounce coin. Now, 5 grams is the same weight as 2 silver dimes, but I don't have a sense of scale for how much metal he drilled out.
Is it possible that one of the rounds isn't pure .999 silver? If it's say 90% silver, it would have to weigh 5.5 oz in order for there to be 5oz of silver.
