What is the correct +/- on the weight of a Silver Panda?

OK, 1 oz = 31.1 grams.

What is the acceptable tollerance on a 1 oz Silver Panda?

I bought a Key Date Panda on eBay and want to weigh it to help determine if it is legit?

I weighed a 1997 1 oz Panda and it weighs 31.1 grams. I am sure it is OK as it was once in a PCGS slab.

I have a Philharmoniker 1 oz Silver that weighs 31.5 grams, it was also in a PCGS slab.

The coin in question weighs 30.7 grams so it seems to be OK to me?

In oz mode on the scale they weigh 1.1, 1.1 and 1.08 oz.

What do you guys think?

Thanks, GrandAm image

    The 28.3495 grams/oz. is the avoirdupois system which is not used for gold, silver and the like.

    Precious metals (PM) use the troy system, i.e. 12 troy oz. = 1 lb. 1 troy ounce is equal to 31.1035 grams.

    The Pandas come in different weights/sizes, but the 10 yuan standardized about 1989 at .999 fine, and 1 troy (31.1035 grs.)

    What year is the key date coin which weighs 30.7 grams (that's a variance of ~ -1.396%)? Frankly, it seems a tad light (I would expect something closer to +/- 0.4%).

    Have a pic? I'm no Panda expert but there are several people that collect them around here.

    I dont know the tolerances, but Mac is correct. 1 troy oz= 31.103 grams. I suspect that 30.7g is acceptable and would not raise any red flags for me. I'd chalk it up to just an underweight planchet rather than a counterfeit coin. As long as the diameter/thickness is correct.

    It looks OK to me but I got it cheap so that is one reason that makes me wonder.

    Bullion coins (even Chinese) should be made to pretty exacting standards. I would consider .4 grammes shy to be out of tolerance for the issue.

    Thats a $100 coin Grand Am. What did you pick it up for?

    Well, they normally sell for much more but I paid $80 shipped.

    It is a mirror obverse, not frosted.

    The diameter and thickness is correct. I have several raw 1 oz pandas somewhere. I will weigh them and see how much they vary.

    The coin itself looks good. The spots on the obverse are from my scanner. The coin itself is flawless. image

    Correct!!!! That IS a mirrored ring obverse, and quite a hot variety. The coin is valued at between $220 and $350. Very nice aquisition, I feel the coin is legit. You were probably going to have it slabbed anyway, so let us know what PCGS says.

    I have one of these myself. It weighs exactly 31.1g on its own, bought from a seller from Netherlands for £71 shipped. Someone sent a some photos of a similar coin to my friend who forwarded to me. He mentioned that the coin weighed 30.9g, 40mm. I didn't get to ask about its thickness but I was told when he scraped the sides, he could see copper ... This is how the coin looks like: imageimage

    I too would think that 30.7g is seriously underweight for a precious metal issue. A mint doing this consistently would be seriously cheating its customers.

    I hope the OP gets it encapsulated and posts the result here.

    I just weighed (10) 1 ounce silver Pandas from different years and they all came in at 31.1 grams.

    30.7 grams seems seriously underweight IMHO.

    I haven't sent the coin in yet but I will LYK the results when I do. I am beginning to have some doubt since the Year 2000 Mirror version has recently popped up all over eBay from China sellers with $0.99 start with $20 shipping and many sell for $0.99.

    I really think someone in China got the genuine dies, the coins look tht good, and are doing restrikes but not sure if they are silver plated or not? image Visually I can see nothing wrong with the coin.

    THANKS for all the help and info, GrandAm image

    30.7g is absolutely counterfeit. Don't send it in for grading, send it back. I have never gotten anything other than 31.10g for silver pandas on my 0.01g scale.

    His scale is fine as he weighed 2 other silver bullion coins that were 31.1 and 31.5 grams. The coin in question weighed 30.7 grams. That is about 1% lighter than what its supposed to weigh. This was probably due to an underweight planchet. As I said in my 1st post, this would NOT raise any flags for me. Its all about specific gravity with precious metals. Since the SG of silver is 10.5, and the SG of copper is around 8.5, I had to rule out copper as being the base metal. If the base metal WAS copper, the coin would weigh around 25-26 grams. But we are talking a mere 0.4 grams out of tolerance, or about 1% light. I seriously doubt that any counterfeiters would go through the trouble to create virtually PERFECT dies and then drop the ball on the weight. This is why I thought the coin was legit from the day the OP made this post. Nice score GrandAm!

    Nice 2004 Construction Bank Commem.

    It ranks up there with the 2006 Anniv Jinan City Commercial Bank in terms of hard to find.

    Low mintages on Both.

    The 2004 Construction Bank is undervalued imo

    When I started collecting Panda's there were very few being sold on eBay in PCGS holders so,,,,,,
