Gorham Heritage...

I recently happened onto a perfect Gorham Heritage urn/champagne cooler. I don’t collect this, or even have any knowledge of this stuff. After searching the web, this is exactly the piece I have with hallmarks, stamps, on the bottom. Can you tell me what the real value of this is, as this seems excessive.

Thanks, Dede
