Good evening Michael,
To address the Acker issue head on- the practical question to ask is whether the marketplace in general is comfortable doing business with Acker these days. The answer is simple- and that answer is yes. Just as with the 2008 banking crisis- the market as a whole decided who would be sacrificed and who would be spared. Acker has been spared.
On the matter of estimates- the strategy there varies from time to time and I would not put much stock in it as a seller. One theory is that lower estimates can induce bidding wars. Another theory is that higher estimates stimulate interest from customers who assume a higher price correlates with a higher level of quality. And there are many variations in between. Note also that estimates often change between the time of appraisal and actual auction.
Hammer price is what matters. Except in outlying cases where you have, for example, a sealed OWC with impeccable first owner provenance or a mix of bottles from different importers and no long term provenance, prices for the blue chips tend to be fairly steady over time- trending up or down, but not highly volatile. Check recent auction results for your wines in lots of similar size/condition/packaging (OWC or not for example) at both houses to get the best idea of what you can expect. Generally, results from the past 12-18 months with the expectation of flat or a very slight uptrend in the near future is realistic.
And yes- the âhandlingâ charge is pretty standard with everyone house I have done business with. It covers insurance, auction prep etc. Ranges from 1% to 5% in my experience- and is negotiable on large consignments except for any insurance component.
As for personal experience, in the past 15 years I have personally consigned 6 figures worth of wine with Acker in probably 10 total placements, 2 of them individually in the 6 figure range. All transportation arrangements were timely, counts and lot listings accurate, and I got my money right on time as promised every time. I was also consulted in advance when Acker wanted to open a bottle or two at the auction or for testing prior.
I have not personally consigned with HDH- but in the past 15 years I have bought a lot of wine from them, as I have with Acker, and have had similarly good results. The only real problem I had was with HDH and some magnums of 1982 Dom that looked terrible, and proved cooked when I opened one, and I was told to get lost when I called them on it (and I called them on it because the auction lot failed to note to label and foil damage as well as the questionable color- but note that this auction happened before the Rudy matter came to a head in 2009-10 and no one was being as careful back then as they are now.)
As an appraiser, I have often recommended Acker and HDH both to potential sellers. I am seldom involved in the final decision process- I just collect data on recent hammer prices and pass on the numbers- leaving the seller to look into commissions and other matters. FWIW- though I cannot give specifics as to why- in such situations my clients almost always go with Acker, as I have done when selling portions of my own collection.
