American coin? I'm not sure?

This probably belongs in another section, but I don't know where. Hopefully someone can help.

I see your query has been moved to the silverplated section. This is an electroplate trade mark of Harrison Brothers & Howson of Sheffield.

Thank you! It's lucky because most of the silver I buy is without any guarantees. But I bought this at a local jeweler who has a small amount of used silver. He vouched for this being silver (and paid a lot more) so I guess I'll return it.
