I have a plate that may possibly be 900 silver. The hallmark includes a figure and what appears to be the letters kso with 900 stamped below. I know 900 usually means 900 silver. I tried to find the hallmark online but no luck. I’m just trying to get some opinions on if this plate could be 900 silver. Thanks.

Thanks for the help. No electroplate markings. Just 900. I guess the chances of it being 900 silver are low though.

It’s stamped with what looks like a “900” mark, so I’m assuming it’s coin silver or a similar purity, but the maker’s mark next to it is unfamiliar.
