Went out tonite to do an area near an old school which has a row of trees near the road. was popping out quarters and dimes with the ace250 when I got a signal jumping between a half dollar and dollar.After digging 13 inches pulled out a plain silver band ring about a half inch wide filled with dirt. Not having my glasses I waited until I got home , and with a 4X magnifier could not beleive what it said in the ring.It said half dollar united states of america e plurus unum.My aunt told me during the depression of the thirties people would take silver coins and make wedding bands from them.This one was made good with no seam.All of a sudden it all made sense.HH Wayne
