coin

J110A/P124

This is the unique 1846 quarter eagle trial struck in copper. This famous trial is also a mint error - one of only 5 or 6 significant pattern mint errors known in the entire pattern series.

After being struck as a quarter eagle, the coin appears to have been placed on top of a half eagle planchet and was then struck by half eagle dies. This is known as a piggy-back rider error. The coin was aligned such that the half eagle obverse was struck over the reverse side of the quarter eagle die trial. Although the quarter eagle obverse was flattened by the half eagle planchet underneath, both dates are clearly visible.

This unique piece is ex 52 ANA lot 4478, 58 ANA lot 469, Bowers and Merena 5/93, Mike Byers as PCGS62BN, Heritage 1/07 as NGC65BN, Simpson-Heritage 9/20 - PCGS65BN.

coin

Doublestruck J112/P126

The following 3 cent pattern shows about a 10-15% rotation between strikings on the reverse.

This example is the former Harry W. Bass Jr. Research Foundation example. It is likely lot 890 from H. Chapman's 7/25/22 sale where it was described as “The reverse twice struck so that the III lies across the other”. The coin was purchased by Virgil Brand and entered into his journal as #122061.

coin

Uniface J125/P147

This uniface pattern trime shows just the reverse. It appears that 2 planchets were fed into the press at the same time as opposed to some kind of brockage or die cap error.

Does anyone have the piece showing just the obverse?

It is believed to be unique and is ex H Chapman 6/1908 Taylor Windle sale lot 1308, Brand (journal #44209), Kelly 2/13/41 B.G. Johnson invoice, Bolt, Numismatics Ltd, Bowers and Merena 6/96, Fred Weinberg, Heritage 9/97, Heritage 11/03, Mike Byers, Heritage 5/07.

This piece reappeared in ANR's March 2005 sale and later in Heritage's January 2006 FUN and 2006 ANA sales.

This is probably one of the most spectacular pattern mint errors known today.

coin

Doublestruck J517/P544

This pattern is believed to have been struck outside the mint from dies sold as scrap that were purchased by Joseph J. Mickley.

2 of the 4 known examples show rotational doublestriking on the reverse.

The illustrated example at the top, ex Crouch-Superior 6/77, Stacks 11/08, shows a 170 degree rotation on the reverse between strikes.

The illustrated example below, ex Bowers and Merena 6/96, Heritage 11/03, ANR/Stacks 11/06 as NGC63BN, Simpson collection shows a 40 degree rotation on the reverse between strikes. This is currently in an PCGS64BN holder.

Flipover Doublestruck J648/P721

This is probably the most fantastic pattern mint error known. It is a flipover double strike ex Stacks 1941 Opezzo sale, Bolt, Numismatics Ltd, Bowers and Merena's 6/96, Bowers and Merena 1/2002 where it is graded ANACS63BN.

coin

Doublestruck J669/P745

The following off-metal indian cent is doublestruck with the second strike 95% off-center. It has been analyzed and found to be 81% copper, 18% nickel, and 1% iron. The finding of this piece, makes it likely that all examples of J669/P745 are actually mint errors struck on leftover copper-nickel stock. The coin is in graded PCGSMS60 but, regrettably, the weight is not given.

Apparently, the piece is ex Numismatics LTD Spring 1983 FPL, it has more recently been offered in Heritage January 2010 FUN, and Bowers & Merena's 3/2010 sales. There is a strong possibility that this coin was earlier in the Col Green collection as one described as “Unc, but misstruck. The only pattern misstruck we have ever seen” appears in the Newman-Johnson inventory of their Col Green purchases as well as in a June 24, 1943 invoice to F.C.C. Boyd. Another from Morgenthau's 5/35 sale is listed as struck without collar, ie a broadstruck mint error.

This is an example of one of the Standard Silver dime patterns struck on misrolled nickel three cent planchet stock or 1969 pattern one cent stock for J666/P741. Notice that the planchet diameter was too small to fill out the entire die face. This is most noticeable at 6:00 on the obverse.

It is unique and is ex B/M 6/96 where described as struck on a three cent silver planchet, Simpson collection, Legend 1/17, Mike Byers and was grade PCGS65. The holder notes the coin as being 76% copper, 24% nickel.

J2132/P2083 Struck on a Quarter Planchet

An example of the 1965 Martha Washington half dollar, J2132/P2083 has been discovered struck on a copper-nickel clad quarter planchet.

The only other examples of this rare pattern are the two on a full cupro-nickel clad half dollar planchet and 6 pieces struck in silver-clad J2134/P2083 embedded in 2 blocks of lucite which reside in the Smithsonian.

These dies serve as the Mint's all-purpose dies and are given out to outside companies by the mint for testing. It is, therefore, not known whether or not this mint error was made inside or outside the Mint.

The illustrated piece, struck from heavily clashed dies, sold in Heritage 3/2003 sale for $29,900 and resold for $21,850 in Heritage 2004 ANA sale.

coin

J2180 Struck on a Dime Planchet

The illustrated piece is one of 2 which appeared in Heritage's January 2010 FUN sale. These Martha Washington pieces were struck on dime planchets from cent dies - notice that the full detail is missing on the left side due to the smaller planchet. The illustrated piece is the nicer of the 2. The other was cleaned and was in an NCS holder.
