Bumblebee Auctions, a website specifically created for police forces, will be used to sell the property along similar lines to eBay.
Previously, the police relied on traditional auction houses to sell such property, but have now turned the internet.
Avon and Somerset Constabulary detained property manager Ken Dawes said: “Sometimes, despite our best efforts, we are unable to return recovered property to its original owner and in the majority of these cases the property is sold.
“In accordance with the Police Property Regulations 1997, the proceeds are used to help the local community by donating to charitably causes, schools, and local community-based projects.
“It is hoped that Bumblebee Auctions will expose these items to a wider audience and as a result generate increased funds.”
Mr Dawes said if an item could not be returned to its owner, it would be photographed and uploaded to the website with a brief description before it went on sale, initially for seven days.
Like other online auction sites, bidders register with the Bumblebee website prior to placing a bid and can then bid as many times as they like.
The item goes to the highest bidder at the close of the sale.
Payment is made online via Nochex and the website contains full, easy to follow instructions.
Mr Dawes said: “Typical items of property which will be sold on this site include jewellery, watches, electrical goods, pedal bikes, tools, CDs and DVDs, and games consoles.
“But there really is no limit to the type of thing which could be offered for sale, so if you do no't see what you are after on your first attempt, try again seven days later and as there are no minimum bids, you could pick up a bargain.”
