Although Property Room runs its own auctions, there are similarities to EBay's operations, including online, 24/7 bidding with minimum increments. The biggest difference is that on Property Room, there is only one seller instead of hordes of them around the world.
Property Room picks up the items from the police departments. In California, the police can generally put unclaimed items up for auction after 90 days, but many are kept much longer if they're evidence in ongoing cases.
The company gets the goods on a consignment basis. If an item sells for less than $1,000, the company and police department split the proceeds. Over that amount, the department generally gets 75%.
Many of the sellers on EBay could give lessons to Property Room on how to take clear pictures of objects and give informative descriptions. On the other hand, Property Room has the advantage of giving bidders only one company to deal with instead of multiple and in some cases anonymous sellers.
