I am disappointed as well, I wanted to send it back but unfortunately there is none available in stock to change it with, so I decided to keep it. Like you, I think I am going to consider it a struck error and I may send it for grading. Thanks for taking your time @SilverJacks to explain all this, appreciated!

It looks like a "struck thru" mint error. It's where a piece of debris, be it solid or liquid, is on the coin during strike. I believe that's the case because I had a similar issue on a bullion coin that, mainly out of curiosity, I sent for grading which came back with a "mint error, struck thru" notation. 
As previously mentioned, it is baffling how a proof coin gets through quality control with this flaw. A bullion coin, fair enough, but proofs should be more stringently checked.
Most people would see that as an unwanted defect. Personally, I would keep it. The coin is not altered or damaged post production. It is in the condition it came when made, making it actually quite unique. I understand anyone's disappointment when seeing it as a defect, which it is. But I like them as they come. They can even add value when particularly prominent, especially if the foreign object is still on the coin, which in this case it isn't, but being centre of the Queens face still has prominence. 
If you sent for grading, you'd likely get the "mint error" notation if you paid the extra fee for it. Although that would mean 69 grade or less, since they do not grant both 70 and mint error on a coin. Once you have "mint error" on the slab, it is collectable, not to everyone's taste, but still collectable to some, including myself. I like it.

It beggars belief that they send a coin like that out, while charging GBP600 for an VF 1959 Gillick.....
One of these businesses that seems to trade off of reputation rather than having a laser focus on quality and customer experience

A brand new proof coin should be nigh on flawless. Yes, it would effect value/grade.

A chap at the mint was likely finishing off one of his Benson and Hedges whilst enjoying a cup of PG Tips and a hobnob while reading the racing post.
A bit of fag ash or hobnob was probably swept into the press as he perused the runners and riders at the 2:15 at Chepstow.
In all seriousness, it is one to send back - quite how this passed Kwality Kontrol, is not surprising but disappointing.

@dicker Looks like he stubbed his benson & hedges out on the Queens face @thesongofthunder that's the obverse not the reverse.

Just a nice 1920 Perth mint sovereign. 

This is my latest pickup a 1942 dated 'Mercury headed' Dime (or 10 Cents), made from .900 silver by the Philadelphia mint.
This coin design was brought out in 1916 replacing the previous 'Barber Dime' coin, it was manufactured unchanged until 1945 when it was replaced by the Roosevelt Dime design.
The first thing that shocked me when I was first looking at wartime versions of these coins was the fascine on the reverse, this was Italy's dictatorships emblem used by Mussolini, and where they got the word 'fascist' from, it was only when I realised that the design was used on the US coin long before he used it and not the other way around.
The front featured what looked like the Greece god Mercury, but I think it was Liberty wearing a winged cap with it meaning freedom of thought.
Many millions of these were made for nearly three decades, different mints, errors and weakness of the strike from worn dies effecting the value as well as condition, apart from whether or not a coin has all its original mint lustre one way to check the wear on these coins is if you can see the separate little bands holding the fascine's together, if the top and bottom ones look one piece (instead of two) then the coin is probably worn, the centre one can also wear down BUT, a coin like mine that has all its mint lustre probably was made from a worn die making the centre band look like a one piece.
The coins were made by three mints, one had no mint mark the others had letters denoting theirs, this could be found bottom left of the fascine.
Philadelphia, no mark
Denver, a D
San Francisco, an S
My coin had a mintage of a colossal 205,432,329 million minted in 1942 alone, by just the Philadelphia mint, so they are common but also not as easy to find in AU/UNC condition possibly due to the soft high silver content in them and long time in service, which to this day are still legal tender in the USA.
 

 

Lovely delivery today to finish off a lovely little set thanks @StackerQueen as usual a joy to deal with. Lucky I got em In before spot went mental 😀😀

A purchase from a new seller/member @Empire with thanks to the escrow service of @BackyardBullion 
Fantastic coin at a super price. 
I’m happy to recommend the new seller and BYB service, which was smooth with a capital ‘OO’.
I’m going to have to flip this one to fund a purchase I’m desperate for, if you are interested keep your eyes peeled or give me a shout!
 

Beautiful piece 

Many thanks to @LawrenceChard Chards @ChardsCoinandBullionDealer For this super purchase! A bit of an oxymoron, Sussie Gold Silver... Fabulous customer service when the system failed on the payment page, spot ran away, yet Chards honoured the deal at nearly a £50 loss to them.
 
They have also dispatched an order made via Platinum Deals that Chards offer exclusively for Platinum members, thanks @ChrisSilver. Again Chards offered a deal I suspect they may have forgotten about, as they set it up back when Spot was LOW! Yet they have honoured the deal without question, letting me buy the cheapest silver available in the UK! Sent today so watch this space...

1 more to go

Ok have a few more coming but the prices while nice for sellers will slow me down a bit.
@ZatStackz Thank you very much for a smooth transaction! (The Silver and copper dragon) And handling my first transaction via the forums.
