CONECA (pronounced: CŌ´NECA) is a national numismatic organization devoted to the education of error and variety coin collectors. CONECA focuses on many error and variety specialties, including doubled dies, Repunched mintmarks, multiple errors, clips, double strikes, off-metals and off-centers—just to name a few. In addition to its website, CONECA publishes an educational journal, The Errorscope, which is printed and mailed to members bimonthly. CONECA offers a lending library, examination, listing and attribution services; it holds annual meetings at major conventions (referred to as Errorama) around the country.

CONECA was formed through a merger of CONE and NECA in early 1983. To learn more about the fascinating HISTORY OF THE ERROR HOBBY and THE HISTORY OF CONECA, we encourage you to visit us our main site Here

    1999 dime face clash

    I think the clash on the face is pmd. But on the reverse there's a broken branch plus a berry on the end of the leaf. Can someone please explain what's going on with it?Image563.jpgImage564.jpg

    Billy,
    I will address all of your posts. The coin pictured here has been damaged outside of the mint. A "clash" is a "die clash". A die clash occurs during the minting process when the obverse and reverse dies strike each other without a planchet between them thereby transferring their respective images onto each other. Every subsequent coin that these dies produce will show parts of the obverse image on the reverse of the coin and vice versa.

    The dots on you coins are mostly likely die chips caused by small pieces of the die "chipping" off leaving incuse areas on the die for the metal to fill up and become a raised spot on the coin. It is a common occurrence on most all coinage. Some die chips tend to "grow" in size over the life of the die. More dramatic chips can become "breaks" (there will always be debates on how large a chip has to be to be considered a break, but that is not the point of this post). Generally the more dramatic the chip or break, the more collectible a coin will be.

    As for the rim anomaly, I am not familiar enough with dimes to make an educated response as to its rarity. But just like clashes, chips, etc. generally the size/location/rarity of any type of collectible coin error determines its collectible value.

    All this being said, I have found it a good practice to hang on to even minor errors to use as references at least until you find some more collectible examples. By studying chips, breaks, clashes etc. you will become more familiar with the minting process and how these errors occur. As you become more familiar, you will begin to find more desirable errors/varieties. These types of errors can also prove to be invaluable as die markers while trying to identify varieties such as doubled dies and mint mark anomalies.

    I hope this helps!

        No problem! Good reference material is a must. I have only been seriously collecting for about 10 months now but have learned so much from studying.
