    @Fred Weinberg
    Since the introduction of Lasers, and electronic Eyes and such, Is there any real mint errors anymore? Since? Very slight Doubled dies. Maybe a strike through but do the Electronics capture most?
    I can just see how a coin counter at a bank spits out coins it does not want and think the mint has to have a 100x better system?
    Thanks Jon

    V. Kurt Bellman Yes, I'm blunt! Get over your "feeeeelings".

    Oh boy! Wait until Fred checks in. They still exist, BOY do they! But just not so many doubled dies, because they now use a single squeeze to make working dies.

    V. Kurt Bellman Yes, I'm blunt! Get over your "feeeeelings".

    You can do your own simulation of standard doubled dies. A hub is a "positive" image, that looks just like the coin's surface, A die is a negative image. You can take your own "hub", a coin, and press it into therapeutic putty (for those recovering from neurological damage) or even that all-time classic, Silly Putty. The putty becomes your simulation of a working die. When you press a coin into the putty a second time NOT in perfect alignment with the first pressing, you have created a doubled die.

    Now, imagine you no longer need two pressings, and one will do. Doubled dies can only be created in VERY limited circumstances.

    I'm not quite sure what you're asking.

    There are no lasers and electronic eyes
    being used to spot errors after they are struck.

    Are you talking about die making?

    As far as errors, it's the Schuler Horizontal Presses'
    that have basically eliminated a vast majority of
    the mechanical errors struck and released -

    In general (and there are exceptions, of course)
    the only mechanical errors (not talking about die
    errors) that get produced and released (since 2002)
    are clips, filled dies, partial collar strikes and some broad strikes.

    Because of those horizontal presses, if a planchet
    is now mis-fed in the collar, the planchet simply
    drops down, and is not struck.

    Because these presses can strike about 600 coins
    per minute, there are still planchets that don't fit
    into the collar just a second before striking, so you
    get either partial collars, or broadstrikes.

    Thanks Fred. I thought that they used equipment to detect any IE: Bad coin and discarded them. So Basically there are still lots of error coins being struck every day and released?

    You have to define "released". If you mean they get out of the Mint, yes. If you mean they survive through the rolling process, not s'much. Rolling coins is done by contractors. In my area, it's done by N.F. String, just a few blocks from where I type this.

    No, in general, off centers, double strikes, and
    most off metals have been eliminated since 2002,
    with very few exceptions.

    With the Horizontal presses being used for all
    denominations except Halves and Dollars (I believe)
    those types of major mechanical errors aren't
    possible under normal circumstances.

    So they are not being struck and caught - they
    aren't being struck (as those error types).

    The last great DDO ( 2015 Shield Cent ) produced a class 4 & class 8 Doubled Die .

    They do use some equipment but about the only thing are what are called riddlers, vibrating screens with different size holes. One with undersized holes lets fragments, scraps, and clipped planchets fall through. Then another with properly sized holes lets properly formed coins fall through, leaving any oversized pieces such as broad strikes off centers. The good coins move on, the rejected pieces go back to the scrap bin.

    I guess I have watched how its made and Factory made to much. Some of those places can discard a pin from a 100# bale of hay, LOL
