New York City Sterling Souvenir Spoon

4.4 inches New York City souvenir spoon with cut out of the Statue of Liberty. I've read in some places that this is sterling silver, and in other places that it's stainless steel. I'm not positive which. Based on the lack of markings, I had assumed stainless steel, but based on the tarnishing that was cleaned off and the bulk of my research on it, it's more likely sterling.
