    It's a quarter with some toning or compound added that appears like toning.

    Why post this here?

    I can’t explain the parallel streaking, but nothing the mint does would make it look that way.

    Perhaps it once had a thin coat of paint. A/k/a surface contamination

    Residues of some sort contaminating the surface. Not a mint induced condition. Worth a quarter. Cheers, RickO

    It looks like a "fluorescent penetrate" coating used in metallurgy to find cracks, especially on welds.
    The process is called "FPI" Fluorescent Pernitrate Inspection.

    It is a 99 Washington quarter with what appears to be motor oil or something on it

    Whatever caused it it is not an error and is worth only a quarter.

    All glory is fleeting.

    5 'W' quarters would be worth something.

    I posted it asking coz I wasn't sure why it looks gold ... why ask me why I posted I'm new to doing this

  • 1999 Quarters also had the errors due to the mint experimenting with the tone for the Sacagawea coins... I've seen a few like this before on forums and such ... only reason I asked

    Spend some time studying the minting and die making processes. The more you know about how coins are made the easier it will be to spot real errors and understand which ones are minor.
