certainly, but it's soft so its best for earrings, a pendant or
brooch that won't get knocked or rubbed against harder surfaces as
often as a ring or bracelet would.Additionally set the bezel just
below the level of an outer frame or railing of sorts to add a mm or
so of protection( whatever your design dictates). Ensure that the
stone or coin as you mentioned, is set with zero tolerance for
movement and that the bezel strip is at the proper height so as not
to cover too much of whatever you're setting,yet to have enough to
hold it firmly..and burnish it around the piece until you become
quite exhausted at the prospect of going round even once more!
I have used 24kt on the outside of a bezel setting for colour with an
inner collar or bearing of an alloy for strength..works quite well.
(and in your case will stretch the small amount of coinage you have
left even farther.
