The upcoming September/October issue of the ErrorScope, the bimonthly journal of the Combined Organizations of Numismatic Error Collectors of America (CONECA), features new finds ranging from a new 1988 Doubled Die Obverse cent to a Double Struck 1972-D Kennedy half-dollar.

Sandwiched in between are articles on subjects as diverse as who hobby pioneer James G. Johnson Jr. was to an article on a foreign doubled die, a Standing Liberty quarter cud, Ike dollar "Peg Leg" varieties and miscellaneous errors on US coins.

Ken Potter writes about a 1988 Doubled Die cent that was first reported by Christopher Beck of FL and sent in by Billy Crawford that features a strong double earlobe that he contends should vie for the same attention given to the 1984 and 1997 double ear cents.

Potter points out that the later two varieties are in the Guide Book To United States Coins, edited by Kenneth Bressett and the Professional edition of the same book respectively. He compares the features on all three varieties and details the probable causes of the doubling.

Rick Emery writes about a spectacular Double Struck 1972-D Kennedy half-dollar that he found while looking through a batch of common-date coins that he purchased from an estate.

In the hoard was a mint-sewn bag of 1972-D Kennedy halves that he said he almost returned to the bank without checking, only to change his mind and find the double struck coin.

Oscar Ernesto Tiznado Moya, a young numismatist (YN) details why he got started collecting coins and describes some of the early numismatic additions to his collection, searching through wheat cents, his interest in the 1955 cent and his purchase of a book on error-variety coins that peeked his interest is this area.

In his article, When It Comes To Split Dies, Things Aren’t Always What They Seem, CONECA President, Mike Diamond suggests that many of the coins now cataloged as Split Die Strikes and believed to be fully spit across the face of the die may not be so. He shows compelling evidence with a series of images that this is an area that needs more research.

In his article, Neenah Double Struck Inlet — ‘Curb Box’, ErrorScope editor, Jeff Ylitalo writes about a Neenah Foundry Co. drainage grate frame that he noticed had the name of the firm double stuck into its curb cover. He photographed the doubling and tied it into numismatics by noting that while taking a walk he found a dime wedged into one of these covers and continued to look as he walked on, saying "dimes add up."

Robert H. Knauss continues his look at Standing Liberty quarter varieties featuring a progression of photos detailing different stages of a 1930-S quarter ranging from a die crack to the eventual failure of the die culminating in a major die break or what many refer to as a "Cud."

Roger W. Beckner shares a German States – Baden 1912-G 3 Mark coin bearing a strong doubled die reverse that Potter has listed in his Variety Coin Register as VCR#1/DDR#1.

Coin World editor, Beth Deisher contributes a biography on error-variety pioneer, James G. Johnson Jr. who joined Coin World as an associate editor in 1960 and in the same year launched two columns, Collectors’ Clearinghouse and Fair to Very Fine. Collectors’ Clearinghouse continues to be a popular feature today. Deisher also sent the 1992 Coin World Obituary on Johnson and a photograph of him examining a coin. A form of CONECA YN Membership named after Johnson for YNs sponsored and paid for by adults.

Andrew J. Oskam, provides a profusely illustrated article on 1972-D Eisenhower dollars featuring to the so-called Peg Leg R of LIBERTY. He theorizes that unlike conventional theory that suggests they were produced though die abrasion that in fact many appear to be from dies that were hubbed in that manner to start.

CONECA Youth Director, Jon P. Sullivan’s, What’s The Error? column features a 1968-D Kennedy half-dollar error. He asks YNs what type of error it is, offering a free cent planchet to any YN that can correctly identify it.

Have you heard of a major ddr on a 51 pr quarter? I can’t send it in until late Oct. I am not good on errors. Also remarkable is how the reverse looks like a strong cameo, with a section of the inner wing (left side) with a mirror like appearance. The strike looks a bit off center. The appearance of the breast looks too heavy, almost caked, strong strike but the features are not well defined – hard to describe. The obv looks like a pr 67. The reverse’s appearance makes it too difficult to grade. Rim letters are… Read more »
