thanks Treasureman, the 2 half pennies I found as I walked onto the target area for the night, they were literally 2 meters apart. I thought I'd hit the jacket pot but then spent the next 20 minutes digging junk or ignoring signals that were most probably cr*p. Just strange that all I seemed to get were half pennies and no full pennies.
I can only suspect that this spot has been worked over repeatedly and the bigger targets have already been pulled?
