Hi Rob,
Many thanks indeed. This was the other potential fit that came up when I was searching. You did well to make anything of the legends, although once one knows what to look for it does become a bit clearer - I believe I can make out the DVB now!
I can follow up with some more research now.
Thanks again,
James
Looks Irish to me. For a start the legend above the crown begins with an E, not an R, so not Richard. And on the reverse, following TAS you have DVB. So I'd say Edward IV light cross and pellets coinage, Dublin. Spink ref. 6373G (old 6365) would fit, or D&F 136 if you prefer.
