1998 1 Oz. Liberty Gold: Mint error or artifact?

I came across this today and wondered how it could have occurred? Planchet defect on reverse?

    Is that the coin or the plastic? My eyes are tired.

    In this case, it's the coin's surface you see,
    not the actual plastic itself.

    Plastic, when struck onto the planchet, leaves
    that 'semi-pl' surface that is the struck thru area.

    @FredWeinberg Thanks for the concise explanation. My eyes were trying to send something to my brain which did not compute.

    @donjalu Did you get the AGE?

    It's actually a 'struck thru' error.

    It's been struck thru a small piece of 'saran wrap' plastic.

    At the West Point Mint, in the Die Room, they cover a large
    tray of new Dies with this plastic wrap, to prevent contamination,
    (dust, dirt, liquid etc.) from touching the Die faces (obv. and rev. dies)

    When that 'tray' is moved to the Press Room, the plastic wrap is
    lifted and removed. It is not uncommon for a piece of the plastic
    to stick to the die, and then strike coins - ergo: struck thru plastic.

    The rarer event is to have the gold or silver Eagle struck thru with
    the actual piece of plastic still on the coin (would be the last coin
    struck like that)....I've had them numerous times on both gold and silver Eagles,

    I know this because I actually witnessed the Die Room trays/plastic myself,
    back in 2004, when I had a floor tour of the WP Mint.

    Is this Canadian 1965 5 cent coin a "strike through" on the bead above the numeral II?

    If it’s moved metal then it’s PMD. If not then might be struck through grease or something.

    Since it’s a Canadian coin you might want to post in the other forum for World and Ancient coins.
