A question about metals

[Salida]

Picked up a ring and a Special Olympics disk.
The ring was dirty like the clad. It wasn't silver as far as I could tell.
No stamp on the inside. It first rang up as a nickel then Aluminium.
Once I got it back home I tossed it in with the clad into my tumbler.
Running my coil over it it NOW registers between .10 .25 and .50 cents.
It just bounces back and forth between the three.

The disk does the same thing. At first when I dug it up it registered
as .10 but now it bounces between .10 .25 and .50 but it looks
like a giant zinc penny.

Anyone have a guess as to what metals these two things are made of?

My guess is the special olympic medal (quite cool by the way) is bronze plated zinc. I've found a few that were. The ring could be anything and without seeing it I wouldn't guess. Friendly advice. Make friends with a local jeweler or pawnbroker and ask for advice. Ask him to show you how to perform acid tests for silver and gold. Then for about 40 bucks you can buy a real good acid test kit. (I recommend getting needles but you could do without them.) Also get a decent magnet and loupe. After looking at rings for a year or two you won't need anything to tell you what an item is made of. Your eyes will tell you.

[size=large]what's the disk at the end of your nickels?
my understanding is the acid chemicals do have a experation date. unless you're finding lots of un-marked metal you may just want to make friends and let them buy the test kits.

My four year old boy lost the 'Leaks Less" car from Pixar Cars when he was two, in Germany. Actualy, another boy swiped it during a church meeting... He was so upset, but got well over it this year when Cars-2 came out, here at home back in the USA.

Thanks for the memory! They really are a pricless find!
