Unfortunately I can't agree that the photo is in any way deceptive. The colouration of these coins (there are many more on the website), especially on the proofs, are exactly the fake colouration blue that I have unfortunately had too much experience of. Often a darker glossy blue for the currencies and a more brilliant royal blue for the copper and bronze proofs(interestingly, any lustrous areas appear less affected, still usually orange/red).
Here's an interesting example that I mentioned recently to someone via a conversation: check out the Cheshire Collection/Goldberg auction 2005. This is still on the web and can be accessed via Google typing in Goldberg and Cheshire collection. Anyway, Goldberg have a good gush about Lot 3032, the 1853 copper proof halfpenny PF65BN, saying "brilliant mauve and iridescent blue toning" and ending their description with "maybe Queen Victoria herself saved this little darling"! Steady on, old chaps....
Well, I bought that exact coin from Spink Numismatic Circular in late 2001, and guess what...it was a dull orange colour, no trace of the colour it turned into a couple of years later. I sold it to a local dealer a year or so later who then sold it on, still as a dull orange proof.
I can tell it's the same coin due to tiny marks and toning patterns being identical, as it was photographed (in black and white) in the original Spink Circular. The Cheshire collection's 1853 proof penny and farthing looked somewhat similar.
I presume that once doctored, these coins can never be returned to their original state, so for a company to be buying up a significant number of British and Irish proofs and basically painting them irreversibly, is rather depressing. I wonder if the proverbial will hit the fan in a few years, or whether it will keep being the emperor's new clothes!
Having said that, I don't disagree with Jaggy that some coins on the website are very decent and sometimes quite reasonably priced. Like everyone else, sometimes they'll have gems, sometimes turkeys.....It also helps if you can recognise the coins from previous appearances in the trade, then decide accordingly. Bottom line - be careful!
