1977 Jubilee Coin in Black and Gold?

Hi. Has anyone heard of this coin (https://en.numista.com/catalogue/pieces5488.html) being issued in a black and gold finish? Thanks.

  Yes - but not for Silver Jubilee of 25 years and dated 1977 like that, but 25 years later again i.e. commemorating 50 years, so dated 2002 - and still has the same reverse of the Queen on a horse ...



 After the original coin (valued at a crown i.e. 25 Pence) was released, some years later the Royal Mint issued the same size coins but revalued them as 5 Pounds and called them crown-sized.
 The coin shown above is described as: 'Elizabeth II 2002 £5-Maundy Golden Jubilee gold proof cased set, FDC. Estimate £4,500. Realisation £5,290'. I found it near the end of this page ...

 It makes sense also that the gold coin was dated 2002 as that was the Golden Jubilee year.

Thanks. The one I've seen must have been plated or coloured afterwards then, I'm guessing, as it is definitely the Silver Jubilee version.
