Have fun with your probably token

Many thanks for your reply - token yes most likely, but is still 15.98g 22ct - and was sold to someone originally for £2250????

 not exonumia - Non circulating coin. 
there is a similarGibraltar  2021 ¼ sovereign in the numista catalog.

I haven’t found anything else yet

Edit to add : yeh 2250 is alot for a ½ ounce bullion coin🫤

Thanks.  Yes, I have also come across the ¼ sovereign coin as well as a full sovereign of the same design by Angela Pistrucci, descendant of the original artist, Benedetto Pistrucci. 

Just cannot find anything ref the £2 coin I have acquired - and don't understand how/why anyone would purchase it for the price of £2250 GBP?

well it is in a handsome case. the  US mint also sells bullion for double its intrinsic value.
