The three most common metals are lead, aluminium, zinc. Lead will scratch easily, zinc will look crystallized when broken, aluminum has 1000-7000 series each has their own sub grouping and hardness and purity.

I think based on it's size/weight it can't possibly be aluminum. I know when i worked at a scrap yard poured zinc could be broken by hand. There is no way in hell i could break the smaller or large piece but i'm sure i can snap the coin looking piece.

I'm going to cut them in half and test a few areas in the center. If the results are the same in the Garbage they go.

Dont throw them in the garbage. Take it to the recycler.

Could they be melted wheel weights? Some of the new wheel weights are zinc. Could lead and zinc be mixed together? In this video he suggests to use a crimper or side cutting pliers to test for lead.

I just brought them outside and leaned them on the concrete and smacked them with a hammer. The coin looking one and the large one broke. The small one won't break. I again tested the center and the liquid goes right to clear. The coin looking one looks flaky on the inside but the large one seems solid

Silver:

File a notch and apply a drop of nitric acid. If the metal is plated it will turn green. if it is sterling, a cloudy cream color will show. Coin silver will show a dark or blackish color.

The color of the acid turned dark in color almost black on 2/3 pieces on both the grinded area and the untouched surface. But when broken in half the test is clear. I also tried 22Kt acid to test for Palladium and the result is clear liquid.

I read how to test platinum you put it in Hydrogen peroxide. I put all three pieces in the small one no reaction. Medium one a few bubbles. the large on looks like an alka seltzer.

Im not familiar with a definitive Palladium test but the Silver test solution should turn RED for Coin silver or Sterling silver and YELLOW for lead, tin, or aluminum. Did you test it on an old dime like I suggested? Dont forget it will leave a stain.

Pure Nitric Acid is not the best test for silver. The only reason they say it will turn green is because silver is usually plated over brass and brass will turn green with pure Nitric.


If you are having trouble or you are not convinced try a pawn shop as a last resort before scraping it out.

It seems you have 3 different alloys. Does the test kit have a Platinum test solution? What do the directions say for Platinum?
