This one, the 1923 South African proof sovereign with a mintage of 655 coins. 

Another gap in my Queen Elizabeth II proof sovereign date run now filled! 

Thanks Chris @SVcollector for these ten George V sovereigns. 
 
A few interesting mint marks; one 1911 Sydney sovereign, two 1918 Perth sovereigns, three 1927 South African , one 1918 Sydney, one 1913 Sydney. Also two 1911 London sovereigns.

I have quite an interesting half sovereign that I picked up on the forum a while back. An 1877-M wide ribbon half sovereign (S-3863), part of a mintage of 80,000 but only thought 20,000 ever minted of the wide ribbon. Only about 50-60 examples still exist (apparently). Its completely battered so not worth more than BV unfortunately but I'll see if I can find you some photos.

Saw this for sale by an Australian eBay seller and picked it up for what I think was a good price. A lovely 1992 UK proof coin set that includes the 50p UK presidency of the EU coin which I understand has a low mintage for a 50p.

Sovereigns are my favourite gold coin to collect and I wonder how many others have a rare or highly collectible sovereign.
I’ll start by sharing the most rare sovereign in my collection, this 1930 Melbourne mint with a mintage of just 77,588 is now difficult to find.
Do you have a rare or unique sovereign? If so please share. 

Probably this one. 1874 die 32 shieldback from the London mint
 
Edit, must get a better photo
