Melt and assay at Sheffield.

[Subspecies]

A few years ago I took some scrap silver to the Sheffield Assay office and had it melted and assayed. They even send the drilling chaff back from when they test it in multiple areas. This is what came back. It has a neanderthal beauty about it I feel ( bit like a mother with an ugly baby).  Makes for an interesting  door stop I guess. Do wish I had it hallmarked though

Awesome.

If you really want it hallmarked send it back in for another assay and engraving! Puts a cost against the value of it for you but I imagine it's a keeper for you anyway? A hallmark on such an ungainly thing (and I mean that positively) would be cool.
