Thanks for the reminder. In fact I'm very careful about condition, and am interested that at the auction unopened proof sovereigns (for example) seem to sell for the same price as bullion ones in indifferent condition. Often there's only me and one other chap bidding for them, and we tend to end up with about half of them each -- with £5 bidding steps I think we're both working to the same maximum bids. I bought one recently for £160 and sold it that same day to Chards for £220 (a date they were wanting). Not quite in Dr Bubb's league, but it made me feel pleased!
