I found this in a creek East of Jackson Mississippi. It was 3 kilos. There is iron ball on it and a section that looks like a peice of metal crashed on the side also has a shape of a bullet or a shoe.

Hi everyone. Slowly building up our kit, Ill post another thread about it later on when I get a chance. Drivung Uber all around, stopping whenever i can at interesting places to detect.. I was wondering if anybody could help identify whether or not this is silver. It sets off my GPZ pretty well and I think I know where it could find a lot more. There's a lot of excavation going on around Reno which is exposing a lot of bedrock and other things haven't been seen for a long time. If this is silver, and there's a lot more is it worth any value? I'm pretty sure it's from ground that's never seen the light of day before. I picked it out of some veins /crevices in this huge buried volcanic rock type. I thought it was the type of iron before, but after thinking about it I think it might be silver. Maybe it's fine gold and crusted on it? I actually thought it was more rust so I took a picture of it.

I found while swinging an old stagecoach route in AZ, I found what i originally thought was a washer or rivet back. after a closer look, it appears to be a thin 17mm brass/copper coin with a round hole. no designs or images, just characters. 4 on one side, two on the other. see photos, silvery look is sun light on dust. After looking closer, its a Chinese coin. thin brass or copper with round hole in the middle. see photos. anyone out there have a clue what it actually is? thanks see photos. any help in identifying would be appreciated.

Hello guys. I'm setting up a 50 gallon aquarium that reflect the local landscape (I live in the UAE, where there are tons of limestones and granites along the hajjar mountains, from my understanding these are mostly sedimentary rocks). I've found a few good stones here (in the pic) in my last hiking trip.

In the vinegar (6% acid) test on them, there was some fizz but only minor and in corrosive areas. There is a common talk among aquarium folks that limestones leach heavy metals and alter PH/Hardness of the water. These usually come from people who aren't really geologists - I was looking for some reliable info on how likely the water (my tap water ph is 7.6-7.8, water hardness 4.0 dgH, carbonate hardness 4.0 dkH) will undergo changes? I do understand it may happen given the aqaurium water ph can fluctuate slightly but shouldn't this take a very, very long time? I would highly appreciate any expert advice on this.
