More silver rings from the "half-dollar" field and finds over four days this week

Recently, most all my hunting has been during the short time between dinner and dark, two hours max and sometimes closer to one hour. I have found very little in the main part of this field which was aerated and had fill added during the summer. The edges continue to be productive but good targets are not as frequent as I hoped. There's a lot of can slaw, screw caps and crown caps to get out of the way.

Hunting along a sidewalk and next to some big pines I recovered two more sterling marked rings about 20-30 feet apart and in the shade zone of some large pines beside the field. Also recovered a small (tiny) ring that I believe is stainless (unmarked) which says "Strength", found along the side walk along with a modern woven bracelet with a metal letter S emblem on it. Last night (Wednesday) along with clad, I dug a beautiful "Engineers" military button that is very probably modern, I just don't know exactly how modern yet. It has a maker's mark that is so tiny I can't decipher it completely. Two piece, back of the button appears to be copper alloy, front had no tarnish on it at all when dug, possibly gold wash. It's my favorite find of the week for sure. Also dug another musical instrument button possibly from a trumpet or other smaller horn that has nice mother of pearl on top. Oldest coins were three Wheaties, no silver coins recovered from this field by me. There may be some still here, but it is in a flood plain and they are deep, probably tilted sideways, and masked.

Hunting with EQ800; 11" coil; multifreq; Pk1; sens@ 18-20, emi dependent; horseshoe mostly off; iron bias@ F2-4; recovery@5.

See the Button Back pic to see if you know the button maker. W, R or B, C, possible O ?
