A double strike would be seen across the full coin, all of the details would be repeated. Because it's occurred across several characters having the same offset I would think it's a die fault, probably some type of hub doubling. There's not much info on die production for Sovereigns of this period so there's a bit of speculation involved based on more modern coin production. https://www.error-ref.com/doubled-dies/ Obverse and reverse dies wear at different rates and the obverse dies weren't numbered. It's possible that other 1872 die 90 reverse coins will have been produced with different obverse dies.

PM just sent!

Nice one, I didn't really expect you to count them all up but it's proof of a match. I've bought from a coin dealer in Cambridge and picked up a couple of rare coins that were listed at the price of a "normal" coin, I guess it's probably the same shop. It might be worth your while checking out his stock, you might find some bargains in there.

Here's a scan of the relevant page from "The Gold Sovereign", I hope this helps. I think your coins is no 445A, which Marsh lists as quite rare. There's a little note at the foot of the page regarding course beading/denticles, it's time you started counting 😃

The Auction coins are now available to view along with a downloadable PDF copy. I've extracted the frontispiece, a very nice introduction from Aydin Izen: The auction link: https://coins.ha.com/c/auction-home.zx?saleNo=3115 Catalogue and download link: https://coins.ha.com/c/ecatalog.zx?saleNo=3115

William Biden was his great Great great grandfather, born in England. He doesn't mention it much...

Anyone worked out what's driving up the recent rise in gold and stocks? I thought the gold price moved conversely to the western stock markets but they've all moved up similar percentages (excluding the FT all share).

Nice certificate, thanks for posting. Maximum coin mintage does not always equate to actual coin mintage though, it's just sets the upper limit.

No, the brilliant uncirculated are struck to higher standard than bullion. The video above explains the difference.

Here's a list of the mintage figures for 2012 gold commemorative coins (Proof and Brilliant uncirculated, excluding bullion) taken from the Royal Mint website The Royal Mint issue sovereigns in 3 standards, Proof, Brilliant Uncirculated (or B.U) and bullion, don't confuse B.U. with bullion. The list above excludes bullion. I suspect the total numbers shown in "The Gold Sovereign" have been used in error and bullion has not been included, which is likely to run to a mintage of 10's of thousands. Does anyone out there know the actual mintage of this coin in Bullion condition? Brilliant Uncirculated sovereigns come in presentation boxes with Certificates of Authenticity. If your coin does not come on the presentation box then it's probably bullion. It would be interested to see how many people own a Brilliant Uncirculated quarter sovereign with a box and CoA.

@LawrenceChard has a very good video on fake sovereigns, about 6 minutes and 20 seconds in he discusses fakes that remind me of yours with additional markings. It's definitely worth a watch if you've not already seen it:

Yes, I'm still looking out for collectable coins. All time high might encourage sales of dormant collections and the chance of some interesting sleepers. I'm speculating here but there may also be a lag in the premium over spot prices on coins at auction etc.

The original photo was a little blurry and the error wasn't too clear so a nice result for the buyer. Just had a look at the PCGS population and there are only 4 of this type.

Well spotted, a very nice overdate with an 8 over a smaller 8. The PCGS image has a die clash, more obvious on the reverse. I wonder if yours has the fault?

You have a good variety of different heads/monarchs already, so may be a good old Victorian shield back would fit into your collection nicely. Then Edward VII, Elizabeth II Gillick.....
