Hallmark on Silver Jigger


I have this silver jigger but can’t find its hallmark anywhere on the web. What do the numbers mean?

In terms of silver marks they mean nothing. The crown suggests that this has been officially approved as a 25ml measure so the numbers are probably an identification mark of the approving body. None of the marks you show indicate that the measure is silver.

I had a feeling it wasn’t silver.

Thanks for your help!
