    1994 Multiple Die Cracks

    Additional Information
    Date: 1994P

    So based on what I found in the LCF Glossary I think these are die cracks. Would these two die cracks be typical of length and prominence? Thanks in advance.

    Those aren't die cracks, they're linear plating bubbles.

    I'm with enamel on the bubbles... Some sort of contamination between the copper plating and zinc core has caused gas bubbles to form... Eventually those will blow out and the coin will look weird or perfectly normal for a frankenzinc

    Here is a little more info to help you out http://www.error-ref.com/subsurface-corrosion/

    From our Glossary -

    Blistered Plating (also called plating bubbles): Gas bubbles that form under the copper plating on copper-plated zinc planchets. Gasses or contaminants that get trapped under the plating expand from the resulting heat and pressure during the strike, causing the plating to push up. These bubbles can vary widely in scope and appearance ranging from small scattered bumps to large elongated or “linear” blisters.
