Why is this edge 2.5 to 3 times as thick?

    This dime is obviously not spooned.
    But what accounts for how thick the edge is here? Is this more than just a misaligned die?

    I will have to weigh it when I get it as I notice several dimes struck on wrong stock (quarter, half dollar) are also on misaligned dies. I don't know what else would cause the edge to be this incredibly thick.

    Any thoughts?

    Would like to see what the experts have to say about this. Weight and diameter will probably help.

    For unknown reasons I have noticed that Philadelphia-made coins tend to have thicker planchets and smudgier details than Denver-made coins. Just today I was looking at a 1996-P quarter I had in my pocket (which are not terribly common out here in the west) and took note of its higher thickness over Denver-made coins. You seem to have an extreme example.

    That's a nice looking fine! Love the double rim.

    A finned rim causes the thickness?

    Definitely another cool one Joe!

    Imho, it looks like mad , double of some images as well the rim looks wrong. Like it’s a quarter rim. Is it the same thickness as a quarter?
    The rim lines grooves is what makes me wonder.

    But why would that make the edge so much thicker?

    "The extra pressure causes coin metal to squeeze into the narrow gap between die neck and collar." Maybe that?

    Imho, finning makes no sense to me. It doesn’t sound correct.
    fin is a thin flange that extends vertically from the rim/edge junction of a coin struck within the collar.

    This is a thick planchet.
    not a thin piece sticking out around the rim.

    It looks like a quarter planchet size. I think the wrong thickness planchet was used accidentally. It’s the only way to cause the thickness. If more people find the same thickness dime. Then it must be on the wrong sized planchet. Wouldn’t you think so?

    If you look at the photos provided it is easy to see the area in question is finning.
    There is a raised "second rim" on both sides of the coin. Look only at the perimeter.

    only on one side leading me to believe this is a misaligned die strike.

    A fin is a thin piece of metal that sticks out that is flat.
    Not a double layer coin.

    Error reference does not show any size height difference. Or go on to say the size of the coin height will be larger.
    Only a thin piece of metal sticking out.

    The extra pressure causes coin metal to squeeze into the narrow gap between die neck and collar.

    So when it does this it’s squeezing it thin like paper.

    Fins start out sharp and are further flattened by circulation, or they fold over.
    This one is double sided which makes the coin thicker than usual.

    So if it was a fin.
    Then how did it get folded back and reeded?

    Still, that wouldn't be struck on a quarter planchet, it would be a dime planchet punched from quarter stock.

    What is the weight and approx. width of the coin please?

    The reverse is misaligned as well.
    If you stack it with other dimes is it the same size there. (Not thickness.)

    No it is not.. It's clearly a Finned Rim that gives it the illusion that it is struck on a thick planchet. It's already established that it's a Misaligned Die strike and part of the evidence of it is a higher than normal strike on one side due to the higher pressure.
