Online it says it could be a aluminum trial penny , whatever that means .

I'm guessing just a discolored regular cent.

Most likely , I'm not lucky enough to hit a jack pot item . Although i would Keep it i think if it was rare .

If it is aluminum , it would weigh less than the copper and the zinc pennies right , or In between ?

[Greenstang]

If it was aluminum, the weight would be .93 g , a lot less than copper or zinc.

Zinc is 2.5 times as heavy as aluminum, and brass is 3 times heavier. (Round numbers)

I didn't weigh it yet , but plan to . I'll post the status here when i do . But it does feel lighter than both , also with my make shift scale i made a ways back . It passes both the copper test and the Zinc , lighter than both . But I'd like to be sure with an exact amount .

Zinc cent that has had the copper plating chemically removed.

They do that to get the copper right ?

[Conder101]

No they do it because either they are bored, or because they hope to pass it off to the unknowledgeable as a non-plated planchet error.  There are real ones that get struck on planchets that accidentally missed the copper plating process and they can be worth over $100.  So some people strip the plating off the regular coins and try to sell them as the error.
