Polie say a Chalfont Borough resident ordered the silver to be shipped to the FedEx store in North Wales last month.
However, someone else picked up the order, according to police.
Police say the man falsely identified himself as the victim when picking up the package.
Photos released by police show the suspect wearing a grey hooded sweatshirt with black lettering on the front, and grey shorts with a black stripe on the side with white lettering "DEPT."
Anyone with information regarding the identity of the man is asked to submit a tip or call Corporal David Interrante at 215-345-4143.
