Weight of a slabbed first strike silver eagle?

[Yeti]

Had a strange experience today, popped into a local jewellers and asked if he had any silver coins and was shown a one ounce coin 2014 first strike silver eagle slabbed up but it all weighed 60grams, obviously the coin should be one troy ounce and I can't see the slab weighing one ounce or do they?

Who's slab?

NGC slabs are about 38.9g

PCGS slabs are about 28.8g

Here is my NGC slabbed US eagle - NGC perth mint dragon to show similar/same weight

 

• 38.9g NGC  holder (from danny) + 31.103g (x1 troy oz)  = 70.003g

 

Although mine maybe fake when i think about it as from these photos my scales look like they have 10g of dust on them

 

Using Dannys weight value for PCGS we can therefore presume it is in a PCGS slab as it is 10g lighter which would get us to 60g. So would be genuine and correct

 

So i say it was Professor Green, with the candle stick in the drawing room - crime solved in less than 30 mins !

This is the one drawback of slabbed coins. At least with an unslabbed coin you can check dimensions weight etc to confirm it is genuine. With a slabbed coin it must be a nightmare and. You are relying on the honesty of the seller.

Thanks for all the replies guys, seems genuine then!

I'm reliably informed that the variation in slab weight makes assuming a genuine coin by co-weighing generally not wise.

It gives you an idea, but it seems the fakers know the combined correct weight and thicken the plastic on the fake slab to make up for the underweight fake coin.

Which begs the question "How do you actually spot a fake slabbed coin?"  Does the magnet test still apply, or is the plastic too thick?

 

Would you hve to send it back to the company that graded it to get them to verify it?

I always buy my slabs from authorised PCGS/NGC dealers,mainly from the USA.

Many of the dealers on ebay have their own websites so aim for the ones that

are accredited and you should avoid fakes quite easily.

 I don't think ive come across a fake modern yet(hopefully)

NGC have a free app if you type in the bar code a picture comes up of the coin and tells you if it is authentic I know many think grading is subjective but it certainly can propel a coins value great collections.com an American auction site recently sold a regular BU silver eagle minted in the nineties for $25 000 because it was the only graded ms70 for that year I know people say buy the coin not the holder but even a ANA show holder can double the value of the coin FS labels do seem like a bit of a marketing ploy
