A few coins, some junk and a detectable rock?

[djm of PA]

Went back to the in-laws yard tonight and found some junk as you can see in the pics. Also found 1976 & 1977 pennies, 1994 Nickel and four quarters, 1973, 1966, 1989 and 1980. All four were within a 24 inch circle! This is the second time I found multiple quarters in a very close proximity to each other on this property, but no silver
The rock in the lower right corner has me baffled, it is detectable on my detector and probe, but appears to be nothing more than a rock? What would cause it to show up

The rock is decomposed iron. It is too vesicular to be a meteorite ! Meteorites are very dense like a trailer hitch ball. I have been collecting and studying meteorites for many years. Cool finds though !!

I Held the rock Last weekend
it is Very light and Reminded me of
coal Slag. (aka, a small black Klinker)

The clean image is much different, thats coal. I live in a 1859 school house and coal was used for heat. Lots of old sites that used coal for heat will have lots of coal to be found. I've seen a lot of the stuff and I can promise you thats coal.

Keep @ it and HH !!

yep I grew up around hard Coal.
& sometimes when it is a Low grade it
dosn't burn to ash.
Especially if there is iron ore in it.

Usually it burns Red (Redish Ash)
But poor coal turns to Red or Black Klinkers
that jam up the coal Grates on occasion.

There is no shortage of that stuff up this way, the klinker hot rocks.

Several suggest coal. Anthracite? Has anyone found coal with a detector?

Others suggest klinkers. Familiar with those, since I live in a state where timber was once king, and wood chips/sawdust/wood debris often burnt to provide power for the lumber mills. Klinkers here were metal debris lodged inside the timber, which eventually melted in the furnaces, producing a kind of low-grade iron ore. Possible, I suppose. A famous meteor-wrong was found inside a smoldering tree in Central Oregon years ago. Turned out to be something like a klinker, though. Made Time Magazine, as I recall, which also thought it was a meteorite. I've got the citation if anyone's interested.

Pure Coal no.

Coal and Iron ore yes

here are some of the requested clean pics, still has the appearance of coal and is not metal, but detectable still.......

Looks like 'coke' to me. We dig tons of it every week.

[nice finds, I love all the "junk" stuff as much as the coins and jewelry
