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

    1955-S RPM#4 BIE Die Progression

    I have recently been collecting (versus simply accumulating) the various Lincoln Cent BIEs from 1955-S, and in the last week or so realized there were undocumented cross-references between the Cohen and RPM listings. After correlating Cohen with the RPM#4 Stages, I have made the following conclusions:

    RPM#4 Stage J = Cohen BIE BA143
    RPM#4 Stage K = Cohen BIE B650

    RPM #4 Stages G, H and I also have similar characteristics to BA143. Stages D, E, and F have the die cracks on E but don't have the chip out of lower first 5. Perhaps they would be listed as BA142 if Cohen was still being updated.

    The Cohen 1955-S BIE B650 / RPM#4 Stage K is one of the most dramatic BIEs in the Lincoln Series. It is so prominent that Cohen gave it a nickname, the "Sausage BIE".

    To show the progression of the BIE die breaks on RPM#4, I took high resolution images of 5 Stages: A, C, E, J, and K, and put them together in an animated GIF. Here is the result:

    For the curious, here are the source images for each stage shown in the animated GIF:

      Very Cool.. I will have to check my stash and see if I can fill in any stages for you.

      I remember back in the Alan Herbert days in one of his books he was touting these and called them BIE cents. I put away hundreds of them. I actually just went through 23,000 wheats that I had purchased years ago looking for E/V and found alot of the 1957D BIE Cents.

        Most of the "action" happens between stages J and K. I'd love to hear from anyone who has a coin with part but not all of the BIE broken out. I suspect such a coin does not exist since it was not documented by Cohen, nor has one ever been documented as a stage of the RPM. Cohen left room in her numbering to allow such a coin to be included (BA143 to B650). If such a coin is found it would be a new RPM#4 Stage K and Stage K would become Stage L.

        I went through my 55-S rolls a while back, and my 54-S and 55-D more recently. I found many BIEs in these searches! I still need to go through my 56-D, 57-D, and 58-D rolls and will be documenting my finds.

          Ray I have maybe 10 rolls that I will go through and see what if anything is in there that may be of interest to you in your research. Its on my todo list..

              Jim...nice BIEs! If you don't have a copy of Cohen you can see the attributions for these on my website at:

              http://www.macrocoins.com/bies-in-high-res.html

              I'm slowly adding high resolution images of all the varieties I find to the website. I actually don't know of an online resource that lists all the Cohen BIE varieties, so I've been putting one together for my own use.

                    Thanks Peter and Jim!

                    I will be adding more BIE images on my website, along with more high resolution / 3D images of various RPMs (including many top100s) as I am able. I will also be going through a bunch more rolls soon and will document what I find.

                    I find high resolution / 3D imaging to be a great tool for identification and attribution. There has always been a big gap between what I was able to view on my stereo microscope versus document in images. Now, the gap has narrowed a bit, and in fact the 3D techniques allow me to do some things I can't easily do even with a stereo microscope.
