while also emphasising Jonathan Fletcher's comment I would also add that contacting the Finds Database of The Portable Antiquities Scheme (
www.finds.org.uk ) should also be done (technically, the PAS only covers England, Wales and N. Ireland, and it should go to the Treasure Trove Scotland site... but that's not working.)- as the discoveries include coinage, that is without doubt trove, under UK Law and is required to be reported.
you could also contact the NMS:

I'd also just note that technically, its probably not a Type R pommel, as its on a post-medieval sword, and therefore not one that really falls under
Oakeshott's typology. I think it may be in one of A.V.B Norman's works for the post-medieval, however.
