Rare 2006 Quarter Errors Worth Money (Full List)

Are 2006 quarters worth anything? Are 2006 quarters rare? You are probably asking these questions if you are considering collecting Washington quarters. If so, our 2006 quarter errors list will help!

The 2006 quarters are part of the 50 State Quarters Program, which sought to celebrate the historical and cultural sites in the fifty states. In 2006, the quarters commemorated sites in the states of Nevada, Nebraska, Colorado, North Dakota, and South Dakota.

Washington quarters might be a popular collectors’ item but they are also only worth their face value. This doesn’t mean they are not worth collecting if you choose the right strategy. One of the most rewarding ways to build your quarters set is to collect error coins.

As our 2006 quarter errors list will reveal, errors can be worth hundreds and even thousands if you know what to look for. So, without further ado, let’s jump in and discover 2006 quarter errors worth money.

1. 2006-P MS62 Nebraska Mint Error George Washington Off Center Strike

An error that comes up in the 2007 George Washington quarters series is the off-center strike. As the name implies, this is an error in which the planchet is struck away from the center and more toward the edge.

Ideally, the die strikes the planchet at the center, ensuring the design is square and balanced. However, sometimes the die and planchet might be out of alignment, resulting in the die striking away from the planchet’s center.

The value of an off-center strike error largely depends on the percentage of the off-set. For example, a coin with a 40% off-center strike will generally be more valuable than one with a 5% off-center error.

In 2023, a collector on eBay paid an impressive $920 for a 2007-P George Washington graded MS62 with an off-center strike error, making this an excellent addition to your collection.

2. 2006-P MS62 South Dakota George Washington Quarter Debris Struck Into Coin Error

Another error that’s worth collecting is the struck-through, which occurs when a foreign or stray object comes between the die and planchet, leaving its impression on the coin.

Examples of stray objects that can make their way through to the pressing hub include pieces of cloth, strands of hair, strings, specks of wood or metal and other such debris. The object usually falls off, only leaving a lingering impression of itself either on the obverse or reverse sides of the coin.

Other times, the stray item may cling onto the planchet’s surface, resulting in a retained struck-through error. This variety is usually more valuable.

In 2022, Heritage Auctions sold a 2006-P George Washington quarter graded MS62 with a debris struck-through error on the obverse for $735. This one too would be a great addition to your quarters set.

3. 2006-D MS65 South Dakota Quarter Die Break Error

A die break is one of the most common and easiest errors to add to your collection. Depending on its shape, form or appearance it can also be quite valuable.

This error occurs when small pieces of the die break and fall of leaving behind small holes that are eventually filled with metal as the die continues working.

Eventually, the metal-filled holes will impress themselves on the coin’s surface, resulting in raised, formless dings or cracks along the coin’s surface. The larger, more peculiar the die break error, the more valuable it tends to be.

In 2022, a collector at a Heritage Auctions sale paid a whopping $750 for a 2006-D Washington quarter graded MS65 with obverse and reverse die break errors.

 

4. 2006-P MS63 Colorado Washington Quarter Collar Rim Clash Error

A rare error that comes up in the 2007 Washington quarters series is the rim clash error. This is an error in which the die clashes against the collar and transfers the collar’s serrations onto the coin’s rim.

You will likely need a keen eye or the help of a professional to accurately identify a collar rim clash, as such an error can be significantly small for detection by the naked eye. Nonetheless, the error can be worth good money.

The effects of the collar rim clash error are more pronounced on reeded coins where the impression of the reeds is left on the coin’s rim.

In 2020, a collector at a Great Collections auction paid an impressive $300 for a 2006-P Colorado quarter graded MS63 with a rim clash error, making this another nice addition to your collection.

5. 2006-D MS66 Nebraska Quarter Air Bubble Lamination Error

There are various types of lamination errors but all of them involve peeling, cracking, lifting or bubbling of the coin’s upper clad layer.

Clad coins such as the Washington quarter comprise a copper core and are covered with several clad layers. When these layers are not firmly bonded to each other, often due to the presence of impurities, a lamination error can occur.

Weak bonding of the clad layer can lead to bubbles forming between the layers or between the layers and copper core. Another consequence can include cracking or even peeling, all of which are recognized as lamination errors, which can be worth a fortune.

Take for example this 2007-D Nebraska quarter graded MS66 with an air bubble lamination error on the obverse side. In 2023, a collector on eBay paid a handsome $1320 for this coin, making it one of the most expensive in the series.

6. 2006-P MS64 Colorado State Quarter Rim Cud Error

The next one on our 2007 quarter error list is the rim cud. A rim cud appears like a lateral raised bump along the coin’s circumference. This error occurs when a piece of the die’s rim breaks and leaves a gap that is gradually filled with small metal pieces.

Eventually, as the die continues striking, the metal-filled gap will leave an impression of itself on the rim of one or more planchets. Larger rim cuds will usually be more valuable, so look out for these.

In a 2022 Heritage Auctions sale, a collector paid an impressive $540 for a 2006-P South Dakota state quarter graded MS64 with a relatively large rim cud error.

7. 2006-D MS63 North Dakota Quarter Broad-Struck Error

Another error you might come across when collecting 2007 quarters is the broad-struck. This is an error in which the planchet is struck outside the collar, resulting in a coin with a larger than usual diameter and a thinner edge on one side.

The collar helps to define the planchet’s diameter and thickness. But, sometimes, a portion of the planchet may accidentally sit outside the collar when the die strikes. This results in a coin with an extended diameter and a thinner than usual edge.

Unlike an off-center error where some of the details might be missing, a broad-struck has all the details, such as the inscriptions, intact.

If you think this is quite a dramatic error, you are absolutely right! It is also on high demand among collectors. For example, a collector on eBay paid a neat $1220 for a 2007-D North Dakota quarter graded MS63 with a broad-struck error.

8. 2006-D Colorado State Quarter Missing Clad Errors

The next error on our lineup is the missing clad, which as the name implies is an error in which a coin’s upper clad layer is missing. It is not uncommon for collectors to pay handsomely for missing clad error coins.

This error occurs when the upper clad layer peels off, exposing the underlying copper core. Peeling can happen due to a weakening of the bonds between the layers.

Often, peeling occurs on one side of the coin resulting in a coin with the copper core exposed one side and an upper clad layer on the other i.e., a partial missing clad error. Occasionally, the upper clad layer may peel off on both sides, resulting in a full missing clad error.

In 2023, a collector at a Heritage Auctions sale paid $870 for a 2006-D Colorado State quarter graded MS64 with a partial missing clad error, making this one of the best errors to add to your collection.

9. 2006-P MS65 North Dakota Quarter Obverse Doubled Die Error

The doubled die is one of the easiest errors to add to your collection but it can also be worth good money. This is an error in which there is visible doubling on some of the coin’s elements, including the devices and inscriptions.

A doubled die error occurs when the die strikes the planchet multiple times at slightly different angles. This can result in some overlapping on the devices and inscriptions, whether on the obverse or reverse side of the coin.

The stronger the doubling, the more valuable the coin tends to be. In 2023, the Great Collections auctioned a 2006-P North Dakota quarter graded MS65 with an obverse doubled die error for a whopping $1005.
