Usually, collections are labeled. See if you can find a referencing system somewhere.
Posted rock is probably chalcedony.

Any value or just a pretty paperweight?

I found this on the side of the road about 10 years ago and I guess my curiosity finally peaked. What is this thing? It isn't magnetic, and it is really light weight.

Hi!!!

Let me try your brain , please?!

Found: East Texas
Magnetic: No

Guess it would help to add pics!! Sheesh some people!! Haha

Looks chert-like to me. Purple might be flourite; if so a knife will scratch it.

chalcopyrite??
Thanks!

Will a knife scratch it? No = Pyrite. Yes = Chalcopyrite. Assay is the safe way to know. Might be more then one mineral.

Slag, possibly.

New to the forum and fairly new to prospecting in general. Here is a picture of a sample I broke in half, one picture is with a flash and one without a flash. I pulled it out of an old mine I found in the western Uinta Mountains. I've searched every resource I can think of and can't find any information on the mine, so I'm unsure of what was being mined. The USGS reports only mention phosphate deposits in the general area. The mine isn't very big, the tunnel is only 40' - 50' long. Mostly I'm just trying to get up to speed on identifying rocks and minerals in the field and was wondering what some more experienced people thought of the sample.
Thanks!

Edit;
Going to take a guess based off the research I've done, please correct me if I'm wrong. I think the host rock is possibly a combination of chert and dolostone/dolomite rock. White calcite vein, the red is possibly iron rich chert/jasper?
I've also added two pictures of the roof/top of the mine, (at the back of the mine), is this layered calcite and hematite?
The sample was taken just below the 'roof' pictures, this part of the mine is very red, it actually stains my hands for a couple days after handling it. The sample itself felt much heavier than other rocks of the same size in the mine, mostly the reason I brought it back with me. Wasn't magnetic enough for a magnet to stick to it, metal detector didn't pick anything up in it (older White's MXT) I have attempted to crush and pan about half of the sample, don't have a rock crusher so was just trying to smash it up with a hammer, was actually pretty hard and more difficult to break up than I thought it would be. Some of the heavies are magnetic, most that are not magnetic have a dull silver metallic/glossy (not shiny) look to them.
USGS geological report says the area is mostly classic sedimentary and carbonate sedimentary.
Any input/thoughts would be greatly appreciated, I've certainly exhausted my knowledge and then some haha.
