Metal Detector Challenge (Night 4) Week 2

This weeks mission of hunting gold rings at low tide has not gone exactly to plan. I checked the tide charts for tonight's treasure hunt, and was disappointed by a 4am low tide. The low tide times are out of whack with my hunting hours at the moment, so I decided to hunt dry sand at a different beach in Sydney's Northern Beaches. As you can see in the attached photos, I did manage to find 3 (UGLY) rings...and a Tiffany & Co 925 Sterling Silver Earring. Unfortunately I did not find the matching pair. Total coin count for tonight's hunt was $36.75 in modern currency. I also managed to find 10 Euro Cents and 2 British Pence. Two of the Rings are 925 Silver, and one is unknown. Looks like gold but the test was negative. Total Silver haul for the night was 23 grams, equaling $13.04 AUD in silver bullion value. So total value of the nights hunt = $49.79. Looks like next low tide is at 4:37am...so another park/dry sand hunt looks like the plan for tonight/this mornings hunt. Next week I am aiming to treasure hunt underwater using my scuba equipment so tide timing will be irrelevant.
