The purpose of this page is to provide you with information about services, clubs, books, magazines, websites, and other items of interest for the variety and error collector. If you come across something that would add to this page, we welcome you to share the information with us so that we can pass it on to those who visit this website.
If you have coins that you suspect are doubled dies, RPMs, OMMs, or other die varieties and would like to find out if they are indeed genuine die varieties, or if you know they are die varieties and would like to find out if they are listed in the Wexler Die Variety Files, you can send them for attribution. When coins are sent for attribution they are examined first to determine whether or not they are actual die varieties. Often times people think they have a doubled die or an RPM, but examination shows that it is one of the other more common forms of doubling that can be found on coins such as mechanical doubling (also referred to as strike doubling and machine doubling) or die deterioration doubling. These other forms of doubling generally have no extra value and many serious doubled die collectors view them as a form of coin damage rather than a collectible form of doubling. If you do have a genuine die variety, we then check to see if it is listed in the Wexler Die Variety Files. If it is listed, we will let you know what the listing number is for the variety. If it is not listed, we will list it in the files for future reference and/or publication. Sometimes we are able to use the new discoveries in our Coin World column or in the columns that we write for The HUB, the bi-monthly publication of NCADD (The National Collector's Association of Die Doubling). We may also feature the new listings on the New Listings page of this website. Several years ago the Wexler Die Variety Files became too large for a single person. They are currently divided up among 3 attributers as outlined in the guidelines which follow. If sending varieties for attribution, please take care to make sure that you are sending them to the correct person. Attribution Guidelines If you have coins that you would like to have examined, or suspected doubled dies, RPMs, OMMs, Repunched Dates, or Misplaced Dates that you would like to have attributed, the following guidelines must be followed. 1. The fee for attributions is $3 per coin. Return postage and insurance is extra and must be included with any coins sent. 2. You may send up to, but no more than 5 coins per shipment. If packages are sent with more than 5 coins, it will greatly delay their return. Five coins will be processed and the package then placed at the end of the mail line until it comes up again. 3. Do NOT send any additional shipments until the previous shipment has been returned. 4. NEVER send coins by Certified Mail. If they are lost or stolen in the mail you will NOT be able to recover any of their value. Certified Mail does NOT carry any insurance. All coins should be sent by Insured First Class Mail or by Registered Mail. By far, the safest way that anyone can send coins is by Registered Mail. It is more expensive but it is the safest way to send them as the package must be signed for by every individual that touches it along the way. If coins are sent by Insured First Class Mail but an actual value can not be determined because the coins have not yet been attributed as varieties, you will not be able to collect any insurance on them beyond face value, or what you paid for the coins if you have a receipt. 5. If you would like to receive a notice that the coins arrived here safely, you can take advantage of the delivery confirmation services available through the Post Office, and also the return receipt services available from the Post Office. 6. Make sure that you package your coins very carefully. If they can move about in the package, they might be able to tear out of the package and become lost. I recommend shipping in a padded mailer available from the post office, Wal-Mart, Staples, etc. 7. Please send your coins in plastic or vinyl flips from which they can easily be removed. Do not send the coins in 2x2’s that have been stapled. 8. We do NOT attribute foreign coin varieties – only varieties on U.S. coinage. 9. Once the coins arrive they will be processed as quickly as possible. Due to large demands on the attributers, it may take anywhere from 4 to 6 weeks before the coins are processed and returned. It is usually less than that but we do ask your patience once they are sent.

NCADD: The National Collectors Association of Die Doubling (NCADD) is a club devoted to die varieties such as doubled dies, repunched mint marks (RPMs), over mint marks (OMMs), repunched dates, overdates, and more.

CONECA: CONECA (pronounced: CO´NECA) is a national numismatic organization devoted to the education of error and variety coin collectors. Its focus is 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. CONECA publishes an educational journal, The Errorscope, which is printed and mailed to members bimonthly and it offers a dynamic website. In recent years the website has offered news stories on member finds, auction results, educational stories, research, etc., some of which are found nowhere else. The same is true of the Errorscope. In the last year, CONECA has expanded its website to include an area dedicated to 20th and 21st Century die varieties (administered by James Wiles) and an Error-Variety Coin Forum where folks can ask questions, give answers, share opinions or theory in addition to sharing images. CONECA is now creating a members only area for the website that should be functional soon and will not detract from existing features that are now offered to members and nonmembers alike.
