Planchet Errors

I apologize in advance for not being able to post pitcures of coins yet. The only luck I've had is a scanned proof set. Has anyone come acrosss a 1975 lincoln cent on a dime planchet. and if so could you post a pitcure please.
I have read a lot about coins being soaked in acid to reduce their size and weight to make them appear to be error coins. Was this being done only in the past ? ( does it still exsists today? ) Also the coin I have is the same size as a dime. It also has smooth edges.

I have compared the edges to other lincoln cents and it looks the same. I have no way to weigh the coin.
Thanks.

    Couple of things:

    1. Is your coin copper, or clad?

    2. Is the size of your coin that of a normal dime?

    3. Does your coin show a copper core?

    For the coin to be on a clad dime planchet, it
    has to be the size of a dime (or a touch larger),
    and have a copper core, and outer clad layers
    like a dime.

    If it's copper, but dime size, the odds are it's
    been altered/cut down.....

    Weight and scans would enable an immediate
    verdict on what it is.......(I know you said you can't do that)

    It's the same size as a dime but dosen't have the reel edges and it's copper. I don't see any clad layer. The lettering on the coin is very thin. Sorry I know this dosen't help much.

    It sounds like you have a
    chemically treated/acid treated
    cent.

    If the coin is copper, thinner,
    and 'mushy' surfaces/lettering,
    it's probably been chemically
    treated........

    Thank you. I appreciate your input. I thought people had stop doing that maybe in the 50's or 60's. With all the ways to detect a altered coin in the past years.... I hope to be able to post photos soon.

    Altering pennies to the size of a dime was more done for the purpose of "tricking" a parking meter or other machine to count it as a dime.
