18.87g platinum ring, 3 gold, silver; 11 coins, 3 jewelry May 25, 2012 06:16PM |
Used noise cancel #11, audio gain = 30 with the 18”x15” SEF coil, Pro coil, and the Minelab 8” coil. Sensitivity level varied depending on coil.
The negative low tides allowed me to venture further out in the pan, and got more old coins than usual.
Day 1. In the pan, used the 18”x15” coil with Auto +1 sensitivity, got a 1929 walking liberty half dollar. My oldest walking liberty and 2nd oldest half dollar (oldest is a 1905 barber half)
Day 2. In the pan, used the 18”x15” coil again. Got my 1st fat Indian head penny, an 1859, my 2nd oldest coin to date (oldest is an 1845 seated dime). That’s very old for Northern California.
Also got a 1906 barber dime, 1955 Roosevelt dime, 1945 WWII silver nickel, and a 1937 wheat penny.
At a different area in the pan, got 2 shallow silver rings (one looks pretty old), and a very heavy platinum ring. It read either 12-25 or 12-27 in the ground. I don’t recall because I thought it was more trash. This is my 2nd heaviest ring to date (heaviest is a 14k 19.67g gold ring).
Day 3. Used the 18”x15” coil in the pan. Got a nickel type signal, a 14k gold ring.
Also got a 1945 walking liberty half dollar, a 1963 Roosevelt dime, and a 1943 WWII silver nickel.
On the beach, switched to the 8” coil with manual sensitivity = 28. Spotted a partially buried thin, hollow, large diameter 14k hoop earring. It was not detectable with the latch open. Laying on the sand with the latch closed, the earring gave a 12-01 reading up to 11” (with the 8” coil). Above 11”, the ferrous number increased (jumpy) as the height increased until it reached a constant 35-01. Above this height, the conductivity value began to change. The strong 12-01 reading is similar to a fast food condiment packet.
Day 4. Tried the Pro coil with auto sensitivity in an area in the pan with large iron junk (previously got the 1929 half dollar and the 1906 barber dime with the 18”x15” coil there). Got a 1964 Roosevelt dime, another 1945 WWII silver nickel, a 1920 wheat penny, and an antique Russwin key.
Tried the rocky area with manual sensitivity >= 25, got another 1945 WWII silver nickel, an extremely worn V-nickel, a very worn mercury dime, and a silver crucifix. Unfortunately the rocky area usually produces very beat up and corroded old coins.
Day 5. Used the 18”x15” coil in the pan. Got a costume jewelry ring with a stone, and a 1939 wheat penny. Switched to the 8” coil with manual sensitivity = 28, and briefly searched the rocky area. Got the desired high ferrous number with the very low conductivity number, a partial 10k gold ring.
ID = inner diameter (in millimeters)
Procoil auto-sensitivity = 16
Rings air-tested with ring parallel to coil, unless otherwise noted
The top 2 rows are the platinum, gold and silver jewelry finds excluding the hoop earring.
The bottom row are groups of the; 3 heaviest ring finds, 3 heaviest gold finds, 3 heaviest platinum finds, and 3 heaviest silver finds to date.
Here’s a photo of the new 3 heaviest gold finds
Here are most of the old coin finds.
A 1906 barber dime, very worn mercury dime, a 1955, 1963, 1964 Roosevelt dimes, a 1943 WWII silver nickel, 3 1945 WWII silver nickels, a 1929 and a 1945 walking liberty half dollars, a 1920 wheat penny, the front and back of a 1859 fat Indian head penny, a 1939 and a 1937 wheat pennies.
The fat Indian head penny is very worn. Normally, they weigh 4.67g, but this one weighs only 3.34g. One the reverse side at the top center, there isn’t a shield, which means it can only be the 1959 version.
The upper left is a photo of the 3 oldest coin finds to date.
A beat up 1845 seated dime, found in the rocky area. The 1859 fat Indian head penny, found out in the pan. And the 1864 2-cent piece, found in a park.
The photo on the right, at the top is a costume jewelry ring with a stone, and the 2 silver ring finds. Below is the ornate antique Russwin key, a silver crucifix on the right (sterling stamp), and 2 other crucifixes.

3 heaviest ring finds: the quarter is used for size reference 14k gold ring with stones (left) mass = 19.67g, density = 12.45g/cm^3 950 platinum ring (top center) mass = 18.87g, density = 20.07g/cm^3 Silver ring with orange stone mass = 16.37g, density = 8.06g/cm^3 (large stone lowers overall density) 3 heaviest gold finds: 24k Gold elephant (Ganesh?) mass = 32.25g, density = 1.37g/cm^3 (hollow with air inside) 14k gold ring with stones mass = 19.67g, density = 12.45g/cm^3 14k gold chain necklace mass = 14.53g, density = 12.97g/cm^3 Just discovered the 24k gold elephant is plated, although it is stamped 24k Sun Shine. Recently attempted to get an accurate density check (I have a list of all gold and silver jewelry finds, unless it’s hollow) by filling it with water. Turns out it is filled with some type of mold material. Got some thin flakes from the object, and it’s plated. 3 new heaviest gold finds: 14k gold ring with stones mass = 19.67g, density = 12.45g/cm^3 14k gold chain necklace mass = 14.53g, density = 12.97g/cm^3 14k gold ring mass = 8.26g, density = 12.33g/cm^3 3 heaviest platinum finds: Top center ring mass = 18.87g, density = 20.07g/cm^3 Bottom left ring mass = 14.63g, density = 20.60g/cm^3 Bottom right ring mass = 10.09g, density = 21.02g/cm^3 3 heaviest silver finds: Silver ring on left mass = 16.37g, density = 8.06g/cm^3 Jesus medallion with blue stones mass = 16.00g, density = 10.00g/cm^3 Silver ring on right mass = 10.61g, density = 4.61g/cm^3 (large stone lowers overall density)
