my own fault really in a way, i should have got clued up first, just a dealer i trusted, he never pushed the coin my way i chose it freely, i had some credit with him and i thought i might do something different as i had started to collect the 20th proofs, 1902, 1911, 27, 37, 50 51 and wanted something a bit tasty if that makes sense, as i would never spend that kind of money on a single coin in cash, from what i gather the rare ones are from the plastic proof set as called because it came in a plastic wallet, , the first portrait of the queen was used but from what i gather it was slightly changed when the coronation set was issued in the red case, and for the one's going into circulation, , the one's in the plastic set is identified by the I in DEI on the obverse pointing to a space between beads on the border, that in itself is not mega rare or scarce, but what is is when they are frosted, the VIP sets were struck from these dies and thats the rare one's, the standard proof has the I in DEI on the obverse pointing to a bead around the border and from a bit of research and whats sold on ebay etc they are extremely common,
the so called plastic set, as you can see they way they were packed they were never be gonna frosty proof standard

i did see the one's on the LCA thing, the plastic type frosted were there but i did see the one i have for about £200 sold, which is confusing cause one sold on ebay a few weeks ago from america for 79p lol, and one for about a quid, exactly the same, so who are these london coins ?? the same ones who sell coins on ebay for a vast mark up ?

i will wait to see what the dealer says or if he comes back at all, this does not sit well with me and i'm not willing to let it go, trouble is he wasn't passing it off as anything other that 1953 frosted proof halfcrown, so i have suggested he id'd it wrong in the first place, anyway anyone with any credibility will do the right thing, esp when they have multiple coins in stock to hand for £50,000 £60,000 plus, thousands of coins in £1000's range etc
