Contributing Editor – BJ Neff
Robert (BJ) Neff became interested in numismatics after retiring with honors from the U. S. Navy Submarine Force in October of 1982. He spent 21 years of service on 4 different submarines in both the Atlantic and Pacific Oceans. BJ Neff retired from the service in Hawaii, while stationed at NSTCP, teaching anti-submarine warfare.
At first, the main focus of his interest in this hobby was with the United States Lincoln and Indian head cents. However, in 2003, after discovering his first accredited variety Lincoln cent, he became enamored with error and variety coins. Since that time, most of his efforts have been devoted to that sector of numismatics.
While serving in the U. S. Navy, he became a qualified instructor and he has taken this learned skill to conduct presentations on various coin topics for the F. U. N. conventions, the Central Florida Coin Club and other local coin clubs. He has also written numerous articles for FUN Topics, The HUB (NCADD’s bi-monthly publication) and ERRORSCOPE (CONECA’s bi-monthly publication). His article in the 2009 summer FUN Topics, “Something New from China?” was presented the “Charles B. Fine” award for best article of that year.
BJ Neff is presently an active member of ANA, Central Florida Coin Club, CONECA, Florida United Numismatists, Fly-In-Club and the Numismatic Literary Guild. He is also a variety coin attributer for Coppercoins.com. Jeanie Neff (his wife) and BJ Neff were presented the Dr. Lyndon King award from CONECA for the most outstanding club member(s) of that organization for the year 2008.
A few years ago, BJ Neff began a new endeavor and developed a numismatic web site called Traildies.com. This site is dedicated to a die anomaly found on both United States and Foreign coinage called trails / wavy steps. In mid 2010, BJ Neff and Mike Diamond designed another numismatic web site named www.MADdieclashes.com. This site provides the numismatists with information concerning the many different and varied die clashes that are found not only on U. S. coins, but foreign coins as well. Both Maddieclashes.com and traildies.com are free information sites.

Consulting Editor – Jon Sullivan
Jon Sullivan became interested in coins when I attended a Civil War relic show which was also being held in conjunction with a coin show. I wandered into the coin show and was intrigued and fascinated by all the coin designs as well as how old they where! I bought several coins and a few weeks later bought a coin price guide and some coin albums and began collecting coins in earnest. A year or two later, I received a book entitled “U.S. Coin Variety and Oddity Guide” by Spadone. The book introduced me to the anomalies which can occur on coins, and I began searching rolls for mistakes, as well as collecting errors and varieties. Later, when I was 13, I decided I wanted to be a coin dealer, and a year or two later, I decided to become an error coin dealer. I currently deal in error coins part-time, and also collect error coins as well as U.S. Type coins. In a few years I will be a full-time error coin dealer.
I live in Tennessee near Nashville, and travel much of year due to my job, which is working as a PDR (paintless dent repair) technician. I fix vehicles which were damaged by hail storms, but due to the small number of hail storms, I have to travel wherever the work is in the U.S. Some of my non-numismatic interests include mountain biking, history, my church, fishing, and business.
