Hi Leo, and thanks for your question. I answered a similar question from another member so I hope you won't mind a copy and paste - there seems to be something awry with my Predecimal account that means I can only post with my phone and not my laptop - so typing is a bit laborious! Any admins fancy having a look at that for me? Some lock file or something maybe?
Unbiased: I wouldn't bother with them really - they do not have the bidder base to be able to provide the high hammer prices that they claim, with the possible exception of bulk junk lots - the Europeans seem to love those. Also bullion seems to do OK - Chinese Pandas, that sort of thing. Serious numismatics is a little beyond them at this stage, and they certainly don't have the expertise to be able to assess serious numismatic items. The UK market is so different from the Continental market, and they don't really get it.
They have no intention of sorting out their images, and will haggle over reserves with a seller till you are sick of dealing with them. They take 12.5% from sellers and 9% from buyers, and those sellers that I dealt with found that too expensive. Buyers will factor the 9% into their bids, so that cost is effectively passed on to the seller anyway. They won't deal in Sterling, and pay you in dribs and drabs, which attracts conversion charges for each transaction. One of the things I was trying to set up for UK based sellers was an aggregated monthly payment, so that they'd only get hit for conversion once a month, but they weren't interested.
Their poor treatment of their sellers has meant that most of the regulars that they had a year ago, say, have got fed up and moved on, so there really are only a couple of UK based sellers left who still use them.
hope that helps!
