Do I have a right to a profit made by a shop owner when he bought and sold my stolen gold coins?

My home was burgled a month ago. Thieves were caught and confessed last week. They had stolen some gold coins that once belonged to my dad. They sold some coins (other coins have yet to be found) to a coin shop and the shop RESOLD the coins to a smelting company so my coins are now totally gone. In my mind, whatever PROFIT that shop owner made over what he paid the thieves for the coins is TECHNICALLY my money. I asked the investigator about this and he said, "Possibly... we could TALK about this all day..." basically brushing me off. It's not MY fault that the shop owner fell for a stupid story from a thief... (said he worked for a recycling comp and these GOLD coins were found in the recycling... PLEASE... anyone that owns these coins would NEVER even ACCIDENTALLY throw them into the recycling bin!) Is it at all possible to get the money for my coins from that shop owner? The thieves should owe him restitution for the money he paid them. Why should I have to pay for their crime?
