Nice haul. Enough silver rings there to make it worth your while to search with a gold jewelry program.
If there's a lot of trash, notch out anything under 43 at 18KHz. That eliminates the foil juice lids that are usually everywhere.
Gold rings seldom come in under 45 anyhow unless they are extremely thin. If its a clean field then run your notch down in the low 20's
That will net you gold earrings and most gold chains but a lot of smaller surface foil.
