Measure the specific gravity. It takes like 3 minutes if you have an accurate scales, a cup of water, and a string. Normally when you find lumps of metal like that, it’s aluminum. If you’re in an area that has native platinum, these could be platinum nuggets.
Depending where you found it it could be manganese.
I found identical looking items in a river bed, had them xray’d at local coin shop and content was 90% manganese.
Turns out there were mines in the mountains that the river runs through, they were slag run off from smelting process.

What's your location? What's the size of these?
I'm a geology grad. We were always taught to take pictures with items of a known size for scale. Usually it was a coin or a camera lens cover, rock hammer, sometimes people for huge features in a road cut.
Location helps the same here too as knowing what country, state, province etc gives a general idea of geology.
I know that Oregon, Seattle and British Columbia have PGMs in placer deposits
If they are platinum, you should be able to heat them to red hot, and then cool. Depending on the impurity level there should be no signs of oxidation on pure platinum.
True, but platinum, I believe, is the only metal that doesn't form an oxidation layer when heated while exposed to O2. It is an almost surefire method to confirm platinum. You can also buy a gold/silver/platinum test kit on amazon for about 30 dollars
My baby gravy mixed with the earth crust to create little lifeless life nuggets for you to find... estimated carbon dating would put that at 3000 years old

Google “Beercanite”. Slag from beer cans.
Slag, probably from a can thrown on a fire
mat is correct

Doesn’t even take that long. If you have lump of platinum of any significant size you’ll feel the density just with bare hands.
Argggggh!! Those be beach nuggets, matey!!
Im I rich?
Only if melted beer cans are worth a lot where you live.

Beercanium!

Found same thing! On a river bed. Magnet will not stick to it
If it's from a melted can it wouldn't be I guess? Aluminium is not magnetic
Did you draw with it. Could be graphite. I found a bunch just like from a river that used to have a water wheel powered graphite factory.
Bubble gum fossil
I believe it may be part of T-1000 but also may be slag.
If they are super heavy they might be meteorites. I've had one that looked similar. Otherwise it's probably slag metal from something
They are heavy and solid. I dont think is melted aluminum
I used to have a certified meteorite and it looked exactly like these.

Same color as platinum nuggets I’ve found before.
Slag
Try a magnet to narrow it down
I find these on the beach around fire pits all the time. Melted beer cans
There is a slight chance these are platinum nuggets. I wouldnt throw them away but continue to pursue a ID. Found on the west coast of USA?

Platinum is a lot denser than Aluminum you can feel the difference,.

Neat, I'm assuming that's U$ 30 , how many tests to the kit.
It's reagent bottles so im assuming quite a few , just search for platinum test kits,
Why not lead?
Lead oxidizes white. It’s usually covered in a chalky white crust if it’s been out in the environment for a while
Thanks man. Very helpful and much appreciated
They might be meteorites. They look campo del cero meteorites.
Just came here to say this!!
Metal
Metal
🚨Slag alert🚨
Slag
Melted beer can (slag)
What does it taste like?
Looks like Aluminium
Could it be a meteorite? Perhaps
Probably aluminum but there’s a very small chance it’s melted silver. You should be able to tell by the weight.
Pure silver.
Pig iron!
silver solder? dentures that have been warped with a lawnmower?
