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

  • Mint mark on parliament stairs or something else

    What is the name of this error? Is it known with 1983 Lincoln penny? Looks like P mint mark somehow made its way on reverse on stairs. It already has a d mint mark

    i will comment but from those images (close-ups are best for such a thing) but i can't be 100%.

    it isn't impossible for a mint mark impression to be other places than intended. one way being a "dropped letter" from being filled in with debris, compacted from striking and then falling out and being struck through the same or usually another coin. pretty rare though.

        For close ups, here is what I recommend if using a phone.....
        • Equipment is everything. You need to stay within a budget, but get equipment that will be beneficial.
        • Good, subdued lighting is vital. Too much glare is never good, and too dark leaves people with a dark image that is not helpful. Be creative, something WILL work ! WARNING ! if you cover a light ensure you uncover it immediately after to avoid any sort of fire issue.
          • If using a microscope, fed into a display monitor, I suggest your display monitors should be at about 50% contrast and 50% brightness (or whatever is “default”) , then you will serve photos that are average looking for most people – no matter what their settings are.
        • Focused photos a vital. Anyone that is going to help will attempt to magnify the photo to see the issue you are seeing and it is absolutely crucial for them to have as clear and focused photo that you can provide.
          • Do not attempt to take a photo with the phone in your hand. Any slight movement of the phone will cause focusing issues.
          • Find a nice sturdy box, about 6 to 8 inches square. Place this on your table or other working environment.
          • Get place a bottle cap or other round object ( preferably smaller than the coin) on the table near the box.
          • Place the coin on top of the bottlecap.
          • If using a cell phone, turn on your camera app.
          • Place the phone on the box, so that the camera can see the coin below. WARNING ! Do NOT hang the phone too far over to cause it to become unstable. Avoid this if it appears the system will cause the phone to fall which may damage the coin and or phone. Use at your own risk .
        • Focus on the COIN and NOT the slab or the flip. If you have a MANUAL focus, this would be best. Out of any flip or cardboard mylar is best. Raw photos work best but if it is already slabbed, you need to try your best to get an in focused photo without any glare from lighting.
        • LIGHTLY tap the photo app to take a photo or, get yourself a Bluetooth enabled key-style fob to eliminate the possibility of the camera moving.
        • CROP your photos. Most phones offer a cropping application within the photo editor. Same the photo as a JPG file. It offers photos that are smaller in size (KB or MB wise).

          I really appreciate that! I downloaded an app that seems to help but not . This will help tremendously. I second guess myself in whether or not I should send a coin in or not. I think I will send this one in. Thanks again!

              We may be able to help identify what this might be. The photos for us seem to be too far away to see what is going on. I cannot determine if it's a die clash, a fragment/lamination issue or nothing worthy.

              Sending a coin in to a third party grading service can be expensive. It's all about return on investment. It's up to you, but I suggest looking at prices for grading and encapsulation at NGC, ANACS and PCGS.

              For example, I know the minimum for an error coin on PCGS is 75 bucks. I don't know if that price is all inclusive.

              ANACS would charge to encapsulate it, plus a verification fee to authenticate the error.

              NGC operates in tiers, they charge an encapsulation fee, an mint error fee and a one time per order processing fee.

              Most will charge an additional shipping fee close to 25 bucks or more, depending on declared value of coin, and number of coins sent. You can research the grading costs at anacs.com , ngccoin.com or pcgs.com. you can call customer service and ask what the full price is, to include return shipping.

              You can also post on this forum. You go to the main forum page and look for CONECA SERVICES. I would go under the examination area and add another post, with the best possible photos that you can get. I'd give them too much info in regards to photos and exactly what you see. The CONECA staff will ten look at your post, pictures and description and either give you an answer on line or, they may request to see the coin in hand and give you more info on how to do this. I personally have not used the CONECA services. I imagine they would charge a low modest fee to look over a coin. I do not believe they encapsulate (slab) coins, but you should get an answer a heck of a lot cheaper. You can then determine if that coin is worthy of sending in for encapsulation. You can send in the coin with any documentation if you wish.

                Oh wow! I really appreciate that. Thank you very much for taking the time to explain this to me. I will proceed with the forum and then hopefully have something and send it in for examination with CONECA. You are right all of those seem pretty pricey and I do appreciate this Organization along with the members. I would rather send it to CONECA. First things first take decent pictures lol. I really appreciate all the help!
