I borrowed an E800 and took it to an old church that was built in the early 1800's. Here you have to dig iffy signals and I pulled the reale out at almost 9". It is a Carlos 4th, 1806, think it is 1/2 reale but I can't tell the mint mark.. I have found larger Spanish silver but none this small.. Can you give me more info on it? . HH Richard
