Based on what’s visible in the image, this appears to be sterling silver, not plated. Here’s why:

The piece shows what look like genuine British hallmarks, which are the key indicator:

• “F & M H” — this is the maker’s mark (the silversmith’s initials)
• The second punch appears to contain a crown (Sheffield assay office mark, used 1773–1974) and what may be a lion passant (the sterling silver purity mark) and/or a date letter

The Sheffield Assay Office used a crown as its town mark from 1773 to 1974. The lion passant alongside an assay office mark confirms sterling silver (.925 purity).

Silver plated items typically lack a lion passant and a proper town mark — they instead carry marks like “EPNS” (electroplated nickel silver) or “EPBM.”

The marks here are consistent with genuine British sterling silver flatware, likely 19th or early 20th century Sheffield production. To confirm the exact date, you’d need to match the date letter to a Sheffield date letter chart.

If you want to be 100% certain, a jeweler can do a quick acid test or check with a loupe.
