Keep at it and you newbies can have finds like mine.:rofl:

I went to the old park to MD today. It is like a walk in the woods.

The big problem here is the ground. It is the worst place that I MD because of ground mineralization. I can't go deep and my id is wacky. Coal is everywhere. This is a typical picture of the coal in the ground.

Lots of people walk the one way road. It is a mile loop and they stop here to water their dogs. I MDed the cracks in the rocks and all around them. Nothing.

A pull tab can read cent and a cent can read foil. Hot rocks hit on silver. Thrash is everywhere. The reason I come here is it is peaceful and there are older coins if you can get through all the trash. I get a wheat or silver every time. This is my trash total.

I didn't MD that long. My newest coin is the 1980 cent. Well the one at the top is probably newer, but I can't read the date. Clad doesn't last in this acid ground. They are not too old, I found a 52 and a 57 wheat. The only thing I know about the metal strip is it is made in England. This is my total - trash.

No matter what you find John, it's always interesting stuff for sure. And you said it best. Swing in the junk, pull the hits and you never know what you will find. I'm curious if you are using a "sniper coil"? Seems like the best thing for that area......

I like your thinking. All MDers find is junk. You should all sell your MD

Have no fear dear John, I've had worse days. I once hunted a huge bark chip playground that looked like " coin heaven". I covered every foot of that puppy and found zero, not even a piece of foil. We all have those days. At least you clened the trash out.

Less the more, uh, bizarre, junk.

I've hunted in a few spots were there was coal in the soil and every time I would get a nice bell tone and coin ID. Dig down and find hunk of coal.:veryangry: Is there any way to reject it other then discriminating out the coin segment ?

I was wondering that, too. Its not metallic, is it? I've found it and dont remember it giving a detectible reaction. Could it actually be the things that often acconpamy it "in the wild," like smelting slag?

 

[awhitster]

Find enough of it and it will keep you warm all winter

It looks like blue-stone from the picture. Many parks put down blue-stone on the driveways and walkways to prevent erosion. Blue-stone has the same effect on a metal detector as coal and coke. There is an easy way to tell if it blue-stone or coal. Leave the path! If you hit the woods and don't get the "falsing" that you get on the roadways and paths, it is more likely blue-stone. My best finds almost ALWAYS are from the areas off the beaten path anyway, especially since the paths in parks are usually by far the hardest hit spots.

If you are using the ACE 250 then you will have problems with hot rocks, as the ground balance on the ACE is pre-set at the Garrett factory.

Coal is a mineral.

This is from Wikpedia.

[size=large]Coal[/size]
It is composed primarily of carbon along with assorted other elements, including sulfur.

Could the small amount of waste products below (metals) be what causes it to be picked up by the detector?

Coal and coal waste products including fly ash, bottom ash, boiler slag, and flue gas desulferization contain many heavy metals, including arsenic, lead, mercury, nickel, vanadium, beryllium, cadmium, barium, chromium, copper, molybdenum, zinc, selenium and radium, which are dangerous if released into the environment.
