Is an Underweight 2001 Scalloped Snake a Fake?
« on: February 03, 2012, 02:27:02 AM »
Hello all. A friend of mine picked up a silver 2001 scalloped snake that he hopes is the real thing  :001_rolleyes: He is a bit concerned though due to the weight. See his comments below.

" . . . still concerned about the other coin I mentioned though. That one is a 2001 Chinese Lunar Snake (scalloped flower). I got it for a great price, but it is not authenticated/graded. My first concern was that it, like your Lunar Snake, is very toned brown around the side. And then, when I weighed it, it weighed in at 30.7 grams. You made me feel better about the browning on the side, but the weight still concerns me. I matched it to close up pictures of NGC encapsulated coins, and can't see a difference, but the weight really concerns me. If you happen to know anything about these coins, I'd love to bounce these concerns off of you.

He sent me some pics on the coin, front, back, and rim, but I'm guessing they're too large to embed. I'll try amnyway, ane maybe get yelled at :)



Any thoughts on this coin will be greatly appreciated!

31.1 grams is 1 troy ounce. The coin your friend weighed is within .04 grams of being 1 troy oz, which works out to 1/10% difference from the nominal weight. That is probably well within customary manufacturing tolerances for the coin. You can go ahead and upload your photos if you want us to have a look. We've got over 10,000 other images uploaded to the forum now, so a few more won't hurt :)

Hi,
I would like to have an explanation about the tolerances on the weight. ( gold or silver coins, it doesn't matter)

The post here above mentionned a weight of 30.7 grams for 1 oz, instead of 31.1 in theory.
badon answered 1/10% ...0.04 gr

I cannot understand !
If the tolerances is 0.001% ( 1/10%=0.03gr), that means from 31.07 till 31.13 gr
If the tolerances is 0.01% ( 1%=0.3gr), that means from 30.80 till 31.40 gr

What is the right tolerance : 0.001% or 0.01% ? That is to say 0.03 or 0.3 gr/coin of 1oz ?
Thank you
