Gold plated vs non-plated

I have two gold plated versions of this coin. Both are uniquely numbered. I have never seen a copper-nickel version of this coin (not plated). Does the non-plated version really exist, or are there only gold plated ones?

I asked about the user who added this coin to the catalogue. Photos are done during night time so hard to say if this is gold plated or not.

When page was created the below link was also added in comment: https://colnect.com/en/coins/coin/78002-1_Crown_Thames_Diamond_Jubilee_Pageant-I77_-_One_Crown_Royal_Anniversaries_and_Jubilees-Isle_of_Man

And we can see here the CuNi coloured coin on graphic.

I searched also in Pobjoy Collector News from 2012 and 2013 but I didn't found this coin at all. Looks like this was made by Pobjoy exclusivly for one of the distributors and Pobjoy didn't sell this coin through their own website/shop.

You are right. I also found the copper-nickel version here on page 8

I had made a link to a website called Coin Update but unfortunately the link is not working anymore. It said:

Isle of Man Thames Diamond Jubilee Pageant Coin

June 5, 2012 By Michael Alexander Leave a Comment

The Isle of Man Treasury have recently launched a collector coin which marks the Diamond Jubilee River Pageant, part of the national and official celebrations to take place from June 2 to 5.

The crown is the only officially issued gold-layered coin to mark this extraordinary event in modern British history.  The £12 million event will feature a seven-mile long procession that will include Dunkirk little ships, historic vessels, steam boats and tugs, Dutch barges and passenger ships. The Golden Jubilee River Pageant will be the focus of the 2012 Jubilee celebrations, marking the Queen’s 60-year reign which features the 1,000-strong flotilla on the River Thames including “Gloriana”, a hand-built 88 foot rowbarge covered in gold leaf. More than a million people are expected to line the route to witness the spectacle – a tribute to Britain’s maritime history – with the Queen’s royal barge as the centerpiece.

The coin’s reverse features a depiction of the Golden barge with the towers of the London Bridge in the background. A cameo profile of the Queen is placed above the barge and the text “THAMES GOLDEN JUBILEE PAGEANT” surrounds the top half of the primary design. The years “1952” and “2012” are seen on either side of the text with the coin’s denomination of “ONE CROWN” under the design. The conjoined portraits of the Queen as she was depicted on earlier coinage and as she is portrayed on contemporary coinage is included on the obverse along with the text “ELIZABETH II ISLE OF MAN 2012” is seen along the edge.

Struck by the Pobjoy Mint in the United Kingdom to proof quality, the coin is produced in cupro-nickel with a 24ct. gold layered finish, a diameter of 38.6 mm, and a mintage of 3,612 pieces. The pageant will take place on Sunday June 3 and travel under 14 road and rail bridges, feature more than 20,000 people on the river and take 90 minutes to pass any given point.

The coin is distributed exclusively by the London Mint Office, for ordering information, please visit their website at: http://www.londonmintoffice.org/royal-commemoratives/thames-diamond-jubilee-pageant-coin/?open=29&cat_id=29

So there are gold plated versions and the current mintage mentioned on the coin page belong to the gold plated ones and not to the plaon copper-nickel ones. Shall I request a new page?

Yes, please.
