Hello all ive just started metal detecting in my local area and have found some standard old coins ie penny,halfpenny but i came across this yesterday and im completely stumped.I can work out the words stone but i think theres some more before it also theres a wreath going around it there was also a date but not in the normal place it was 1881 but there was a 28th before it it read 8th1881 it looked like a 2 before the 8 but its now fell off as the coins condition is very poor.Im not after a valuation just what it may be.It is 30mm across thanx in advance.
