Types of error coins with photos<\/h1>\n\n\n\n

Planchet Error types of error coins with photos<\/h2>\n\n\n\n

Planchet error coins are focused on issues related to the planchet itself. These planchet error coins may have occurred whether it was done prior to being sent through to the upsetting mill which shaped the blank with a rim. Without travelling through the upsetting mill, planchets are considered type I planchets. After the coin has been sent through the upsetting mill, and have a rim, they are considered type II planchets.<\/p>\n\n\n\n

Clipped planchet types of error coins with photos<\/h3>\n\n\n\n

Clipped planchet can be mild or extreme. They can also e rounded, straight or ragged. <\/p>\n\n\n\n

The machine which punched out the planchet, simply hiccups, and punches a new line of planchet <\/p>\n\n\n\n

in an area that has already been punched out. Somehow the clipped planchet escapes the mint, usually in bags.<\/p>\n\n\n\n

These types of errors are much sought after by error collectors when the clipped area is between 20 to 60 percent on modern coins, and 10 to 40 percent on older coins.<\/p>\n\n\n

Incomplete punched planchet<\/h3>\n\n\n\n

An incomplete punched planchet occurs when the sheet of metal is inserted into the punching machine, but the machine has an issue. The strip either gets stuck, slips, or moves too quickly. The tool which punches these planchet could simply be dull, and requires maintenance. Overlapping attempts to punch a planchet out of the strip will cause planchets to be either incomplete punched planchets or clipped planchets.<\/p>\n\n\n

Lamination types of error coins with photos<\/h3>\n\n\n\n

Lamination errors can occur before or during the minting of a coin. The lamination error is usually associated with the metal alloy in which it may have been rolled improperly, have the wrong metal content per layer, or be extremely brittle or flakey. <\/p>\n\n\n\n

Lamination issues that were introduced onto the metal strips that planchet are punched out of will eventually be struck with the lamination error already present. <\/p>\n\n\n\n

Lamination errors can be made when striking the coin If conditions are conducive for it. The most common lamination error is usually associated which an application of grease. When a planchet is struck by working dies the pressure exerted onto the planchet along with the grease can cause a suction, and some of the planchet metal may be removed in this process.<\/p>\n\n\n

Wrong metal types of error coins with photos<\/h3>\n\n\n\n

Wrong metal error coins can bring a very big premium. It really depends on what type of metal it is. From transitional errors, where a coin should be silver and is clad, or should be clad and it is silver, to totally wrong metals as well. There are coins struck on wrong planchets, such as half dollars struck on copper cents, nickels and quarters struck on copper cents plus US minted coins struck on foreign planchets. Additionally, world coins struck on wrong planchets as well.<\/p>\n\n\n\n

Cuds types of error coins with photos<\/h3>\n\n\n\n

Cuds are marginal die breaks. They usually touch the rim to qualify as a cud. This one has been submitted for inclusion to the Cuds on Coins database. I made a purchase directly from India for ten of the exact same error coins.<\/p>\n\n\n\n

The coin has been added to the Cud on Coins database: CU-2R(IN)-2015-01R .<\/p>\n\n\n

Die breaks or cracks types of error coins with photos<\/h3>\n\n\n\n

Working dies are used to strike planchets into coins. Over time, like anything else, these working does are subject to wear and tear. Eventually these working dies are subject to stress cracks and die breaks. These can happen for a variety of reasons. Die breaks and die cracks are displayed as raised lines on the coin, in jagged form. The photo below shows a major die break which the mint workers would have taken out and replaced because this die is past its life expectancy.<\/p>\n\n\n\n

If it was allowed to continue much further, the die would eventually fall apart and crumble. Die cracks like this one that are dramatic in nature, might fetch a nice premium. <\/p>\n\n\n\n

The Lincoln cent below does qualify for the “retained Cud” designation. A retained Cud is simply a cracked die in which a portion of that die should be able to fall out, but has not.<\/p>\n\n\n\n

This coin is designated as: RCD-1c-1952-01<\/strong> (cross reference is: SKH-1c-1952-02D)<\/p>\n\n\n\n

When dies begin to fail, it is pretty evident. The photo below shows a Lincoln cent that is within a few thousand strikes before it would shatter. Lincoln’s head is primarily where die cracks emerge on he cent due to this area being one of the largest and deepest cavity on the die.<\/p>\n\n\n

Die Caps (Capped Die) types of error coins with photos<\/h3>\n\n\n\n

Capped Dies are planchets that when struck as coins, adhere or stick to the hammer die. The coin will produce a small number of Brockage<\/strong> coins, and then will produce struck through capped die errors, that resemble one sided coins. <\/p>\n\n\n\n

With the hammer die capped, the planchet will progressively become thinner and thinner, as each strike will cause the metal to climb up the sides of the die. The die will remain capped until a mint worker removes the capped die or, it eventually breaks free from the die, since the die cap is so thin.<\/p>\n\n\n

Die chips types of error coins with photos<\/h3>\n\n\n\n

Clogged Numbers and BIE error coins are primarily caused by debris settling between the numbers or letters. This debris can be minute flakes if metal that is sheared away due to mechanical imbalances when the planchet is struck into a coin. <\/p>\n\n\n\n

Combine the metal flakes with grease which may result in some of these areas becoming quite dramatic. Typical locations for the debris to accumulate are on the date, mintmark or LIBERTY on Lincoln cents. But any location close to a device (number, letter, building, etc) can be game for die chips to accumulate.<\/p>\n\n\n

Mis-aligned die (MAD) types of error coins with photos<\/h3>\n\n\n\n

Mis-aligned die (MAD) error coins are associated with the improper installation of one die on the minting press. When a coin is struck, one side of the coin will appear normal, where the other side of the coin will be slightly out of alignment.<\/p>\n\n\n\n

This differs from an off-center strike, where the obverse and reverse are both off center.<\/p>\n\n\n\n

This type of error is sought after by a select amount of error collectors and does not seem to bring a high premium.<\/p>\n\n\n

Multi-struck types of error coins with photos<\/h3>\n\n\n\n

Multiple struck coins are coins which get delayed leaving the striking chamber of the minting press. The minting press is operating like a high speed jack-hammer. It only takes a very short period of time, probably tenths of seconds for a coin to be multi-struck. The coin remains in the striking chamber, usually out of the collar. <\/p>\n\n\n\n

Normally after a successful centered strike, something goes amiss and the coin is not properly ejected. It may sit on the edge of the die, uncentered and receive an additional single strike or several additional strikes before being cleared out of the striking chamber.<\/p>\n\n\n\n

In my opinion, there are two categories for multistruck erros coins; appealing with dramtics and mutilated. People tend to show reluctance to purchase higher end error coins because they are uncertain about the condition and value. Add in a coin that has been pulverized almost to the point of not being able to recognized what it is, and the negatives within one’s mind may add to a person passing on the mutilated coins. <\/p>\n\n\n\n

A nice premium can be had on appealing and dramatic multistruck coins. These coins are becoming rare, due to the US Mint not allowing errors to escape the the mint since 2003.<\/p>\n\n\n

Off-center types of error coins with photos<\/h3>\n\n\n\n

Most off center error coins sit on the anvil die off center. Most will be struck out of collar or will have a partial collar at best. The partial collar will show reeding on limited area of the off center coin. <\/p>\n\n\n\n

This is another popular error coin with collectors, and not many above 15 % have escaped the mint since 2003.<\/p>\n\n\n

Split planchet types of error coins with photos<\/h3>\n\n\n\n

A coin that becomes a split planchet after the strike usually occurs due to the metal alloy being compromised. The planchet itself was brittle, improperly rolled or had other imperfections within the metal which under stress split in two.<\/p>\n\n\n

Brockage types of error coins with photos<\/h3>\n\n\n\n

Brockages are pretty complex to explain. First, we have a blank planchet placed upon the anvil die ready to be struck into a coin. The minting press strikes the coin, but it sticks to the hammer die becoming a Die Cap. In the photo below, the hammer die was the Reverse die, since we have no reverse die present. <\/p>\n\n\n\n

With the reverse die covered by a planchet, and the planchet was struck, the coin has a successful obverse image on that capped die. Now, another planchet is fed in between the capped reverse die and anvil die. The dies strike the planchet into a coin. This coin will have a good obverse, but the reverse will have a mirror image from the capped die from an earlier strike.<\/p>\n\n\n\n
