    If on a quarter stock, should weigh around 5.670 grams; so if your scale is accurate at 8.8 grams, it is not struck on a quarter planchet. However... definitely lighter than the normal 11.34 grams expected for a half dollar. Perhaps struck on a foreign planchet?

    Also, what does the reeded edge look like... does it look like a clad coin, or is it solid metal of some sort? Magnetic? Aluminum? Perhaps a contemporary fake?

    Hello again From Numsimatic News Dated Jan 09 2009 by Ken Potter disagrees with your assessment. Thank you for your post. I do tend to do research before making such claims. I try to be as factual as I can.
    Hope this article helps. https://www.numismaticnews.net/archive/kennedy-struck-on-quarter-stock

    He said on quarter stock, not on a quarter planchet.

    The quarter planchet is thinner than the half dollar stock, but was punched in that [quarter] strip, and is therefore, larger & heavier than a quarter planchet.

    you found a genuine error.

    what CaptHenway says goes.

    it's a half dollar sized blank, but cut from the metal already rolled for the thinness of a quarter. this is why it is the right diameter but underweight.

    congratulations.

    That's a real nice find. Yes - "Stock" vs "Planchet" is a big difference.

    Interesting. What does the edge look like?

    Somebody compiled a table of the weights of incorrect stock errors, either here or on CT, but I haven't been able To find it

    Attached is a link that shows how to calculate the correct weight for these errors, if anyone is interested

    You do not seem to understand what a wrong stock error is.

    Planchet stock are those big rolls of really long sheet metal rolled to a thickness appropriate to only one denomination. Punch a quarter-sized blank out of quarter stock and you get a perfectly normal quarter blank. Punch a half dollar sized blank out of that quarter stock and you get something heavier, because it covers more area, but not a normal half dollar blank because it is thinner than it should be. That makes it lighter than a half dollar blank but heavier (and larger) than a quarter dollar blank.

    I hope this helps.

    Agreed... brain fog on my part, thinking planchet.

    arby96, thanks for posting the article link. Absolutely a nice find!

    I have a handful of these. Easy to tell when you hit one because they sound different than regular halves. Always a fun find, congrats!

    Now that is a very interesting find. I have not seen a Kennedy half on incorrect stock before.... There have been other coins posted here of that condition. Cheers, RickO

    Here's an old thread where I explain the math for figuring out wrong stock errors.
