What is the going rate for an auctioneer's commission?

Paulette asks:

What is the going rate to pay an auctioneer as a commission fee?

AW says: Hi Paulette, believe it or not, it’s considered unethical, even illegal in some states for licensed auctioneers to state commission rates. Such disclosure could fall under “price fixing” laws. 

I can tell you that it’s not uncommon for an auctioneer to propose a sliding scale. For example a lower commission percentage on higher ticket items, and a higher commission percentage on lower ticket items.

Hope that helps.
