August was once the quietest month in the auction business but a look at this year’s auction calendar tells us that scheduled events are increasing. To this point we have 34 events posted, up from 26 in 2011 and 12 in 2010. There are many contributing factors for the increase but it probably most comes down to busier schedules.
The following are our statistics for August for the past eight years. The first chart shows the number of auctions and lots by year – 2005 to the present. The second shows that August is not a fluke. The total of all auctions for the January-May period has also seen a substantial increase.
