State Quarters error coins are coins from the 50 State Quarters series, 1999-2008, collectible due to their errors.

Background and Description

The 50 State Quarters programme saw the United States Mint issue a series of circulating commemorative coins. Between 1999 and 2008, it featured each of the 50 U.S. states incorporated in unique designs for the reverse of the quarter.

The programme intended to create a new generation of coin collectors – and in such was very successful. It became the most successful numismatic programme in history. Half the population of the United States collected the coins, either casually or seriously.

One area in which the programme generated particular collecting was the error coins. It in unknown whether these errors were deliberate, as of course the intention was to make these coins collectible, or accidental. The error generated considerable interest from collectors.

Errors include:

2004 – Wisconsin errors

There are three different Wisconsin State Quarter error coins, all around the design of the ear of corn featured. One error is the inclusion of an extra smaller leaf. Another is a ‘low leaf’ pointing downwards, and the last is a ‘high leaf’ pointing upwards.

2005 – Minnesota errors

The Minnesota quarter featured the error of an extra tree in the design.

2005 – Kansas errors

A few of the Kansas quarters featured the error ‘In God We Rust’ printed on them, as well as some featuring humpback bison.

2005 - West Virginia errors

Die breaks on reverse at either 4 o'clock or 8 o'clock.

2008 – Arizona errors

Die breaks caused some extra cactus leaves on some of the Arizona quarters.

Other errors:

There was another error coin in the first Delaware quarters, which were made with a disproportionate rate that led to machine vendors rejecting it.

A major error occurred when the obverse of a 2000 state quarter was combined with the reverse die of a Sacagawea Dollar, and printed on a dollar coin planchet. Only 11 examples of these ‘mules’ escaped from the mint.

There are a number of other errors including die breaks, off-centre striking, planchet clipping, die cuds, grease strike through errors and missing layers. There may perhaps be some that have not been recorded yet.


As the state quarters are still in circulation, lucky collectors may find error coins among their general change – so keep an eye out! Otherwise, examples of these error coins can be found on auction websites such as eBay, or through coin collectors clubs and exchange forums.


Generally, individual error quarters can fetch up to a few hundred dollars. However, individual error coins have sold for as much as $1,500 in the past.

A set of all three Wisconsin error coins sold on eBay for $300 in February 2005.

Sets of all the flawed coins have sold on eBay for up to $2,800.
