I believe they were struck from sand-blasted dies for photographic purposes but that's only hearsay. The photos were taken through a slab but, as Freeman states, "the obverse is in extremely low relief".
The sets were probably struck very early on in the process when they were still using a variation of the George VI toothed reverse in preparation for the 1953 penny. When I sent my 1953 pattern mule to the Royal Mint for comment, they replied that it had been probably struck in October 1952. Another example is held within the Royal Collection Trust, noting that it was struck as a Trial on 17th Sept 1952.
I've had terrible problems with Fedex doing this before. I did once get them to go back and renegotiate with Customs to get the VAT reduced from 20% to 5% but I've overpaid many times. I now refuse to use Fedex - I ask the auction houses to use UPS who always send you a form to indicate the nature of the goods and they always charge the correct 5% on numismatic items.
I emailed Semra a week or two ago saying I assumed it would be a commission-only auction and she confirmed that it would. Also, the hard copy catalogue makes no mention of the Grange Hotel.
JLS, I've added the picture in its current state and will replace it if you manage to smarten it up.
Would you like me to attribute it to you personally (if so, let me know your name) ?
Thanks, Paddy, that tip is absolutely priceless. Like Gary, I have sometimes deleted something by accident or dragged something by mistake into oblivion and that single action would have fixed it. I've just tried it and it works.
Thank you again.
Might this be a 2 over 1, Mike ? Freeman states that sometimes the minutest trace of the 1 can be seen and your photo suggests something at the top of the 2.
I would be vary wary of DNW at the moment with uncatalogued lots. They have recently sold Hiram Brown's collection of copper and bronze and they parcelled many of them into multiple lots with no regard for the content. If care had been taken to catalogue the individual coins, they would probably have doubled the price paid. Your coins are almost certainly not of the same quality as Hiram's but I imagine DNW would only offer them in bulk lots.
In the process of creating my website of halfpenny varieties, I'm finding it much more difficult to differentiate between halfpenny varieties than penny varieties. Some of the differences are so slight that it must be a nightmare trying to identify worn specimens.
