Metal Detecting Coins


With this article I hope to answer as many questions as I can about metal detecting coins.

Can a metal detector find gold coins?
They find veins of gold fairly easily, but can sometimes battle to find smaller sized items, such as a gold coin or a small nugget.

Can a metal detector find coins?
Every metal detector will discover coins – whether it’s a $50 piece of equipment or $10,000. Coins are metal, and metal detectors will find, well, metal. You do not need a “gold” detector to find gold coins. Gold detectors are suggested for nugget hunting – not coins.

What is the best metal detector for coins?
This one can probably be debated among other detectorists, but overall, the Garrett AT Pro is the best well-rounded for coins, relics, and fresh water. The Fisher F22 is best for beginning youngsters, and coins. The Minelab Equinox 800 is ideal for relic hunting. And of course White’s Metal Detectors are arguably the best detectors out there.

What’s the best frequency for metal detecting?
Ideally you should be using low-frequency coils (anywhere between 3 to 7.5 kHz) to look for large targets. The lower the frequency of the coil, the deeper your detector can look into the ground.
Low-frequency machines at 2-4 kHz are best metal detectors for deep coins, mid frequency 5-12 kHz for relics, jewelry and coins, and higher frequencies for gold.

How do you clean old metal coins?
This is another highly debated topic. Tidy old coins with vinegar. To clean up an old coin with vinegar, pour a cup of vinegar into a glass or dish, and after that carefully set the coin near the bottom. Allow the coin soak for a couple of mins. After that understand the coin by its sides, draw it out of the vinegar, and wash it clean with distilled water.

How do you clean corroded coins?
Wet the coin completely with clean water. Roll the coin in baking soft drink. Scrub the deterioration away making use of a toothbrush or dustcloth. Rinse the coin clean. Repeat the scrubbing up and rinsing up until the deterioration is eliminated. Load a plastic container with an acidic compound, such as tomato juice, orange juice or vinegar.

Does cleaning old coins devalue them?
Cleaning it will harm the coin’s surface area and also substantially minimize its value. Simply put, you must never ever use dips, gloss, or chemical services to cleanse your coins.

Should you clean old coins before selling them?
The most vital thing NOT to do is clean your coins. Cleaning up rare numismatic coins will substantially decrease their worth. Although you do not lose a lot by cleaning up a coin which derives worth only from its silver content, it’s not worth the risk.

How can I tell if my gold coin is real?
The Acid Test – Make a small mark on the piece of gold to pass through the surface. Drop a small amount of liquid nitric acid on that particular scrape and then wait for a chain reaction. Fake gold will instantly turn green where the acid is. Gold-over-sterling silver will end up looking milky. Real gold with do nothing.

How deep do metal detectors detect gold?
Low-frequency machines at 2-4 kHz are best metal detectors for deep coins, mid regularity 5-12 kHz for relics, jewelry and also coins, and also greater frequencies for gold. The majority of regularities will choose up coins, however detectorists have most success between 6-15 kHz -and even more particularly 8-12khz.
