The Lighter Side of Coins and Currency
Errors, Varieties, Found in Rolls, Unique and Interesting Coins and Currency
This 1987D Washinton Quarter is the victim of multiple errors. It is extremely well struck for an off center coin and then triple clipped as well. The errors together create an interesting almost gear lilke effect on the coin. It sold at action in April of 2015 for $164.50.
A capped die is caused when a struck coin sticks to the upper hammer die. Once the coin is stuck to the die face, the reverse of the struck coin becomes the new die face. When the next blank is fed into the collar and the strike occurs, the reverse design of the adhered struck coin impresses itself into the new blank.
This wartime Off Metal error was created when a Steel Cent Planchet got mixed in with a batch of Wartime Nickel Planchets and was then fed into a nickel striking chamber. This example sold in Jan, 2015 for $3,760.
2007 is known for shatterd Die Roosevelt Dimes. It is one of the better errors to come out of that year. Shattered Dies occur just before a die reaches catastrophic failure. This is known as a Terminal Die State. Shattered Dies are easily identified as a series of intersecting cracks and often lead to retained cuds on the serface of the coin. These coins retail for anywhere from $200-$350 depending on conditon and severity of the damage.
The FlipOver Double Strike is rarer than a standard doubleStruck coin. These coins begin as a normal, standard strike. they are then flipped and return into the striking chanber, in collar and restruck. This example sold at auction in Jan, 2015 for $1997.50
This 1971S Roosevelt Proof was struck while a series of fine threads lie between the planchet and die. The lines that appear in the field to the left of Roosevelts image are the rememenenants imprinted into the surface of the coin. With just over 3 million proof dimes minted in 1971, this error is both interesting and valuable. This example is in the private collection of Robert Risi.
This die cap has the "bottle cap" effect that is so desired on such errors with a high, raised rim all around. Instead of being ejected from the dies after the initial strike, the piece stuck to the obverse die, and was repeatedly struck against a series of newly fed planchets. The additional strikes caused the edges of the error coin to wrap around the collar of the obverse die. On this particular die cap, the rim is unusually high. The obverse design is extraordinarily sharp, and there are no recognizable design elements on the reverse--all of which indicate that this is a late-state cap. This is rare on lower denomination coins, when errors are more frequently encountered, but it is extremely rare on a large denomination coin such as a dollar. This example sold at auction in 2006 for $29,900.
This Madison dollar was struck on aluminum scrap, from a fragment from a planchet feeder. The scrap is roughly rectangular but has ragged edges. No date or mintmark is present since the irregular diameter prevented passage through the edge lettering device. Lustrous with light gray toning and most of the major devices present. This example was sold at auction April 2012 for $8,050.
Significant portions of the dime show through after the 1976 dime was restruck by Bicentenial quarter dies. Much of the detail on the obverse remains and makes for a very eye appealing error. Bicentenial errors are popular - in general - with collectors. This example sold at auction in Jan 2012 for $9,200.
This 1999P Die Capped Roosevelt dime is a stunning example of the error. It occurred when the first dime adhered to the obverse die during its strike. The dime was then struck at least two additional times, bonding with two planchets fed between strikes. This example sold at auction for $3,737.50 in April of 2008. The current owner is Mr. Robert Risi.
While this is an example of a two planchet Bonded Pair any number of coins can be fused together by the pressure of the minting process. In cases of a large number of coins being fused, it called a stack or bonded pile-up.
This Kennedy half had the rare occurance of being struck through sheered off or detached reeding. The reeding of another coin was clipped off of it's original planchet and found itself lying on top of this planchet as it was struck leving behind the full reeding design on the surface of the newly struck Kennedy. This is an incredibly rare and very cool phenominon.
This reverse fragment separated from the remainder of the coin after the strike. The separation was caused by an alloy impurity or other flaw within the planchet.
On a proof press, a coin was first struck in the usual way, but instead of completely ejecting from the dies, it flipped over and partially out. A second planchet entered the dies, and the striking of the second planchet bonded it and the first planchet together.
The first strike was normal but the coin was struck an additional two times, once 85% off center toward 7:30 and once 95% off center toward 6 o'clock. The two off center strikes are at 5 o'clock and 10:30 relative to the first strike. The date is complete on the 95% off center strike and mostly complete on the first strike. None of the strikes are uniface.
This 1976 Kennedy proof is missing a significant portion of its reverse lamination . The damage appears to have occured after striking. This coin was sold at auction for $493.50 in April, 2015.
