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

    I am very new to coins and came across this Wyoming Quarter, I am uncertain about the cause of the errors. I haven't ever taken or sent pictures of coins so I hope you can view them. On the obverse side there is an imprint on Washingtons head as well as in front of his nose and in back of his pony tail. A line of silver (die break?) is in front of his nose. On the reverse another imprint is across the horse spilling onto the sides. Please excuse any wrong terminology and feel free to correct me. Any information or comments would be appreciated.

    Hi Linda and welcome to the CONECA forum.

    It appears that you have what we call a die clash. That happens when the dies meet and there is no planchet in between. So, the dies actually impart some of their design features onto the opposite die. In this case you see Washington's bust on the reverse side and what I believe to be part of the horse on the obverse side.

    From the looks of it, this may be a recent die clash, for there has been no attempt to take of the clash marks (which the MINT does do, especially on the obverse side).

    I hope that this gives you the answers you seek on your coin and if you do have more questions, please just firer away.

      This is not a die clash. The coin was struck through hardened, compacted die fill, possibly cooked lubricant or an agglomeration of grease and metal dust. Such "grease strikes" are common.

        Must have been tired last night. Looking at it a second time, Mike is right, it is not a die clash as I had thought, but instead struck thru grease. The marks on the obverse and reverse dies just do not align properly for a clash.

          different view

          Thanks for the replies. I am happy to know that it was difficult to classify. I am sending a few new pics along due to my review of the edge/rim under the microscope this AM. I mostly focused on the reverse side as it is newer and perhaps has more appeal to me. I can't take the exact pics due to shadow but I want to show that there is damage to the edge/rim of the coin. Along some of the inside rim there is a definate ridge very tight against the rim. The edge also is flattened at points and there is a linear separation along a small portion of the edge-rim. Some tiny drops of silver are found in the depressed edge.

          Don't know if this much matters but I found it interesting. So sad that my coin went from interesting to mundane in a matter of minutes. I'll keep on searching.

          So many coins so little time...

            I don't see anything anomalous about the edge or rim.
