Auction houses are in business to make money. But in business, reputation matters and when an auction house starts to get a reputation for being a bit dodgy then their business is going to suffer. Some of the coins, acquired at LCA and that I sent to NGC were fine and got decent grades. But some did not. So the results were a bit hit or miss. But when you are paying out good money for a coin on the basis of the auctioneers photos and description then 'hit or miss' simply isn't good enough. Fact is, none of my DNW, Buckland Dix and Wood (remember them) or Glendinning's coins came back with problems.
So, in the confidence stakes, I now perceive buying from LCA as being high risk. Will I buy from them again? Yes, but only if the coin has been slabbed or graded by NGC or PCGS. That, for me, takes most of the risk out of buying from them. I will not buy CGS slabs because 1) there is a conflict of interest with LCA, hence risk, and 2) they are not generally accepted in the marketplace.
However, I will continue to use DNW and Heritage. I am also happy to buy from Spink and Baldwins if they can get the user interface right and have material I want. But confidence is a fickle mistress. Hard to win and easy to lose. Businesses take note.
