Leu is the only auction house I engage with where my default MO is to approach auctions like shill bidding occurs.
With that said, whenever I start feeling that way, I’ll win a coin significantly below my max bid and am left scratching my head.
I do believe more transparency around bidder IDs would help. CNG gives you a paddle # so it’s easy to see who is winning each lot. But then I ask myself: if I knew that all lots where I thought shill bidding occurred were won by the same paddle, what does that prove?
I just wonder if Leu attracts a certain clientele with deeper pockets and so the feeling of shill bidding occurring is the natural outcome. Unless hammered coins show up re-listed in subsequent auctions, I don’t see how shill bidding could be proven outright. Even if the person bidding you up was the same for each coin, you yourself are also bidding on all those coins, so maybe it’s just your doppelgänger? 🙂
So, all this head scratching does is guarantee that I’ll never place a bid in a Leu auction with more than 10-15 seconds left on the timer. That’s the best safety precaution I can think of. And it’s worked out pretty well; about half of my collection is from Leu at this point and nearly all of them I’d say I won for a fair price.
