    I know the value is most likely face value but I think they are nice to look at.

    Thin film interference? o_O
    You lost me there. Can you explain what that means?

    It's one of those science things about toning. It's over my head so I just call it toning.

    Very much the same as an oil slick on water.
    When the thickness of the film is in the area of the wavelength of visible light some colors are refracted (or defracted?) and that's what you see.
    I believe the thickness is in the 400-700 nanometer range (VERY thin).

    That's a new one, film interference. I like toning better. I understand that word.

    Can you post some full size photos of the top 2 @Mark479
    They have some neat tones. Love the golden,
    When you upload them. Once uploaded
    Click on the full size option it is easier for us on mobile devices.

    Thanks.

    If we are talking pretty coins I like this one though its probably not worth anything its easy on the eyes... I like the halo. Im noticing the pic doesn't do the color justice.

    About the halo, copper coins when minted has a patina formed on the surface from the pressure that inhibits corrosion to an extent. When a coin is circulated like the 1967cent of yours , the original patina is worn away from wear, and becomes more easily corroded ( or toned to some who like it) while the patina in the more 'untouchable' areas keeps that more of the original mint coloration, IMO, Jim
