Apparently someone here messaged her in her dimondgirl guise and addressed her as 'marleybob' - he says she never replied which doesn't surprise me in the least!
Thanks Mike, I should have noticed that as I'd asked DNW to send me the catalogue for the auction. It's a good thing to have on the shelf, sitting nicely alongside the Colin Adams catalogue.
Yes, possibly Canada.
His biography says he moved abroad in 1976 and that his youthful interest in coins was rekindled as recently as 2006 when he spied a 1797 cartwheel twopence in a Toronto dealer's shop, bought it, and the rest, as they say, is history.

My guess is that "1933" object will at some point be relisted with a shocking asking price of between £50K to £100k. It will then attract more than 50 "bids". Bidders tend to have feedbacks of 1, 0, 179, 705, or private. Then it will be relisted again with some excuse about the "bidder" wouldn't pay up. Then the game will repeat itself.
