I am not sure... But I would suggest using a metal detector. Hope it works!
I have researched this topic and found that you can indeed find precious metals when using a metal detector. These metal detectors will detect items such as silver, iron, metal, gold and platinum.
GOLD!!!
Gold because it is worth alot of money and is very hard to find. Silver because it is hard to fond and also costs alot of money. All metals are precious but the rare ones are the most precious because the harder tho find the more it costs.
Metal detectors cannot find gems or diamonds because they are not actually metals. Instead, metal detectors can find silver, gold, titanium, and other precious metals, which can be worth quite a bit.
The prices of precious metal fluctuate rapidly. You would need to find the spot price for each on any given day to find the price equivalence.
Some metals are considered precious because there harder to find and the monkey in the center of the earth might like the metal to eat at night. just jokeing the real reason is because its harder to find some of the metals and depending on the minarels in the metal
Precious Find was created in 1996.
