    No value attached to a "solid" mintmark. It's due to either a chipped letter punch, a worn letter punch, or die deterioration. As you say, quite common.

    Cents with brass-colored plating do exist, ostensibly for the reason you mention -- too many zinc ions in the copper plating bath. They don't carry much value, so sending them in to be...

    It's an off-center strike on a straight-clipped planchet. Its appearance is typical for this error type.

    Since there is no known minting process that can generate a bent coin that is otherwise normal-looking, I would have to conclude that the bending occurred after the strike. In other words, not an...

    There are way too many cuds to remember all of them. Base-of-bust cuds are among the most common and they really don't stand out in one's memory.

    I can only tell you that the grading services do a poor job when confronted with errors that are subtle, obscure, novel, compound, or complex. They're not all that reliable with respect to simple,...

    The 1955 cent was plated and set in a bezel (jewelry housing).
    The second cent appears to have split after the strike. If it's underweight, that would support my remote diagnosis.

    I certainly see an S-mintmark, but we'd need a close-up image to determine whether anything else is going on. A date would be helpful, too.

    This is the normal streakiness seen on an unstruck planchet. A thin layer of lubricant in certain areas of the die face was enough to prevent the streaks from being erased by the strike.
