    I have 2 1953-d pennies that weigh over tolerance...one weighs 3.27 grams and the other 3.33 grams. Can you tell me what can cause this to happen? Is the year and mint just a coincidence?

    One is .16 grams overweight and the other is .22 grams overweight. Both are struck on thicker than normal planchets. They are considered Rolled Thick planchets.
    Definition: Coin metal strip is sometimes rolled too thick. The resulting blanks, and the coins derived from them, are thicker and heavier than normal.
    The first is slightly out of tolerance and the second is way out of tolera3 and can be considered a more desirable error.

    Has nothing to do with coincidence. The issue can occur on any year and mint.

    The correct weight should be 3.11 +/- .13 grams (2.98-3.24) They're not off by that much and the only thing I can think of is a rolled thick planchet. I doubt if it adds much value to the coins.

    Technically they should weigh around 3.11 g and as said rolled thick planchet . Good luck . Hope this helps .

    Strip the blanks were punched from was rolled VERY slightly too thick.

    When I have a weight "issue" I first suspect the scale and try to eliminate any possibilities of that. I actually have two scales and use both when I question a coins weight. I'm not saying that is the problem here, but it's the first thing that comes to my mind.
    An accurate caliper may help. Just a thought.
