The seller did mention in description that the lot ‘includes four restrikes / facsimiles’, which in another word means - fake. He did say that in other listings as well. 

Finally, this beautify has arrived! Superb! Thanks @SilverStan
 
 

So, theoretically we should be able to work out thickness ourselves if we know the weight and diameter and the density of the metal，because a coin is in a cylinder shape, and calculation is to work out the the volume 😂 . If the weight is known, then divide it by the density, we would know the volume. And then divide the volume by the area of coin’s face which is π x radius x radius, then we can get the height which is the thickness. 😂😂😂
However, it will not be 100% accurate though because a coin is not flat on surface, and also affected by number of decimal points chosen. So the result is more for indication purpose. 
Most time if I need to find a coin’s thickness, I just google. Some dealers websites may have information for some coins, eg Sovereign’s dimensions can be easily obtained. However, need to bear in mind that thickness or diameter is not an exact fixed figure. It is a range. 
Therefore, the best way to check if a coin is fake or not is to have it tested, and it is better to use non invasive methods, for example XRF (can work on directly on the metal to show its composition but not good at if the metal is in packaging), Sigma verifier (can work on the metal if it has thin packaging but can’t show composition and only limited to certain alloys or coins), Specific Gravity Test (cheapest method but need a bit time, and result may be affected by various factors in the process). Sometimes one method can’t give you a solid answer, so you still have to do cross check using a different method. 

Strange , because that security sticker looks very similar to these for sale on eBay for £2.39 

Imagine the joy on your face if the wife bought you that for a surprise gift at Christmas  .

No way , it's amazing. Id say a MS 80 plus all day long. 😆

No it is not real. It is a fake. And it is just a PCCB slab, not slabbed by NGC.🤣🤣🤣

It has a sticker on it so it must be real . Even though it looks like the chocolate coins you get the kids at Christmas. 
 

More to it is that now it has 2 bidders already and one of them has 1596 feedback. 

I have acquired all of the Queens Beasts 1 oz Gold Proof Coins of which I am very proud and lucky to possess. I would be very interested to know if anyone else on TSF has the same and has them all Graded? I’ve asked on two other Topics in the forum but sadly no response.  I’m in two minds about grading when it comes to Rare Coins! I enjoy them in the presentation box they come with what a beautiful sight. I understand that Collectors only buy the best and from a buyers point of view quite rightly so but given there are only, at the most 380 Sets Worldwide buyers haven’t got that much of a choice anyway! Food for thought. If Grading then I’d go for The Completer which really isn’t part of the Set but a complimentary Coin which I think is the most  stunning of the whole series. Any thoughts advice or Pro + Contra about Grading would be most welcome. 

Stay Safe y,all Regards and greetings from rainy old Germany

Many sources which you would expect to be accurate and reliable are not, including the Royal Mint. As most journalists, dealers, authors, etc, simply believe what they find on "official" sites, the misinformation gets repeated endlessly, until everybody believes it, often including the original source of the misinformation. 🙂
Thickness might sound simple. If coins were plain flat discs, like blanks or planchets as the Americans call them, and without any milling or bevelling, it would be easy to publish and use thickness data. This also assumes the surfaces are reasonably flat and regular.
As we all know, coins are not uniform flat discs, with the possible exception of 2013 gold and silver Britannias, which come pretty close. 🙂
Even simple dimensions like diameter are not precise. For example, the published data on the diameter of a gold sovereign is 22.05m, a "fact" which many TSF members probably know, but...

This is a 2021 gold sovereign, a proof which as we all know are minted to the highest standards. We calibrated or zeroed the calipers before use. As you can see, the reading was 21.93mm, a discrepancy of .12mm, or 0.544%. As the area is proportional to diameter squared, this would increase the error, to 1.085%. Add in, or rather multiply by any error in the thickness measurement, and any results are likely to be suspect at least.
In case anybody thinks using a £10 vernier gauge does not lend itself to precision, we did the same thing with a Leveridge gauge, a specialised type of micrometer:

With similar results.
Now for the thickness or height measurements:

There is a third height measurement, namely the highest parts of the design on both sides. The height on each side is known as the relief.
Which depth / height measurement would you use?
Perhaps an average?
In which case, mean, median, or mode?
Now add in striking differences, such as rim height, which is known to be subject to considerable variation.
Have I introduced enough variables?
...or too many? 🙂
 

Well, just trying to be helpful, which I have helped other members here before. But I totally can understand where you come from. Good luck. As I said, you could try Hatton Garden where it has lots of jewellery shops.

Brilliant, thanks.
He should be there on London Coin Fair - Saturday 4th September

@LawrenceChard Chards is the best! 😄I promised to Ian at last London Coins Fair to say it when I get a chance. 😆

It looks okay to me. One, where did you buy it from? If it is a reputable dealer, it should be fine. Two, you can measure the coin by weight, diameter and thickness, and then compare with the official figure. Fake coins cannot fool all three together. Three, you could try specific gravity test. It is not too much difficult and no damage to the coin, there are plenty videos on YouTube. Four, you could try a pawn shop or jewellery shop to test for you, or if you are in London, I am more than happy to help you test it as I have a Sigma verifier. 

You can't get a much better offer than that!

Just for peace of mind, it is always better to have it properly checked. 

I’m a private collector. You could go pawn shops, jewellery shops, or dealers’ stores to have your precious metals tested. They usually have xrf machine in stores and should be okay to test for you. Otherwise, you could always say you are thinking about selling, and they have to check authentication first before giving you a quote, at which point you will know if it is legit for what you have. But I believe most people would be just happy to help out.
