Help Identifying

A piece of silver was donated to our rummage sale fundraiser and a customer mentioned we should check into the markings to get the history and information on it before trying to sell it. I haven’t been able to ID the markings and thought no better place to check than here. Hoping someone out there can shed some light on it for me. Thanks!

I’m not absolutely sure, but I think it’s an American silverplate mark. I can’t put a name to it though. However it’s almost certainly not silver as it doesn’t have any indication of fineness.

Thanks for checking in to it!
