A couple more hours of park hopping produced the following. The 1/2 real was at 8in. I passed over a zillion dime and penny signals at 5in but when the trusty T2 says, "hey dummy... consistent penny signal (80) at 8in" I dig, and dig carefully! Thanks for looking!
PS Oh yeah...on the left is the largest button I've ever dug, shank attached.
PPS ...and that ring is sterling.
