This is just like a home tester.

Just have dig it out and put the batteries back in.
The Whites 6000DI might be able to get a read on the metal content.
The minelab gold monster 1000 will tell me if it's non ferrous metal.

The one with the white gunk is a standard corroded cent.
Stay tuned for the weight and metal composition if my High tech tools still have good batteries
Caliper measurement 18.88mm

Minelab gold monster 1000 reads Non Ferrous metal 100%
Whites 6000DI meter picture says it's gold well something else in that range. Hmmm,

Now a Visual inspection with the EyeCrometer
Not sure which would be the Obverse or Reverse.

At that weight and size, I'd guess it's a Zincoln core. I can think of a couple of tests to do on it, but they're kind of destructive.

 

Wouldn't want to ruin a good specimen with a battery of destructive tests, now would we?

 

Would we consider tests that are destructive if it's zinc, but not if it's silver?

 

Zinc, Yes. Silver, no to destructive testing.

 

Put it in vinegar. If it bubbles, it's probably zinc, and definitely not silver.

For bonus points, hold a flame near the surface of the liquid where the bubbles are coming up. They're hydrogen; you'll get little blue flashes, maybe even pops.

Edit to add: if it doesn't bubble, it still might not be silver. I'm not sure nickel would bubble. Platinum won't, either.

 

How about Palladium ?

 

Nope. Nor rhodium, iridium, or osmium.

Cesium would make a BIG pop.
