Good I'm glad it's helpful. Here are some
State Quarter errors/var. also
(

2004-D WDDR-001 doubling on right side of buffalo nose edge and also a die damage error/extra leaf on corn stock(cold be high or low leaf. These are just die dent type of die damage tho.
Minnesota
2005-P
2005-D
2005-S
Look for a small "extra tree" literally floating in the sky next to the fourth evergreen tree to the right of the state outline. There are at least 54 different reverse variety types on P mints and 6 different reverse types have been found for the Denver coins, and 4 types for the San Francisco Proof coins,
2005-S Kansas (proof) hoof-shaped die dent on rear of bison.
2005 Kansas quarters created a humpback bison
Kansas quarters sporting the motto "IN GOD WE RUST"
Oregon
State Quarter 2005 P,D,S Doubled Die CDDR-004 Doubing under tree branches and below the mountian.
California 2005-P
EXTRA FEATHER CALIFORNIA
State Quarter ERROR
2006 P South Dakota
Broken left Wing
2006-P Nebraska look for Die Break making the rock formation look like a VOLCANO with flowing lava.
OKLAHOMA
2008-P ON THE REVERSE , THERE IS A RAISED AREA ON THE BIRD'S WING THAT LOOKS LIKE AN EXTRA FEATHER
New Mexico
2008-P Extra cactus.
Arizona 2008-P This variety is very prominent and completely covers two of the three letters of the designers initials (JFM) so that only the (M) is exposed
Alaska
2008-P
THERE ARE 2 SPOTS WHERE WASHINGTON IS MISSING HAIR. BY HIS EAR AND ABOVE HIS EAR ON OBVERSE. Look for extra bear claw on reverse also.
HAWAII 2008
on one of King Kamehamea's feet makes it appear he has an extra toe, hanging over the edge of the platform he is standing on.
Experimental Planchets
There are approximately 15 known 1999
State Quarters struck on Experimental Planchets. All five states in the 1999 series (DE, PA, CT, GA and NJ) have been discovered.
These Experimental
State Quarters have sold for as high as $10,000 each, depending on which state, the coin's condition and which type of experimental composition was used.
There are four known types of experimental compositions which have been discovered so far on 1999
State Quarters.
Type #1 - This type has the "color" of a
Sacagawea dollar and has the copper center core.
Type #2 - This type has the "color" of the
Sacagawea dollar but does not have the copper center core.
Type #3 - This type has a slight "green" color and has the copper center core.
Type #4 - This type has a slight "green" color but does not have the copper center core.
Here are a few "telltale" signs to determine if you have discovered a
State Quarter on an EXPERIMENTAL PLANCHET in circulation:
WEIGHT - The weight on ALL of these discovered so far is OVERWEIGHT - varying from 5.9 grams to 6.3 grams.
SIZE - It is slightly THICKER than a regular
State Quarter, due to the heavier planchet.
COLOR - So far, the pieces discovered are either the same "color" of the
Sacagawea dollar, or have a slight "green hue" to them.
LOOK - The edge is slightly rough and may have a higher rim around part of the edge.
EDGE - Some of these do NOT have the center COPPER CORE.
STRIKE - None discovered so far are proof-like in the fields.
REEDING - Some of these have incomplete reeding.
These coins were analyzed by spectroscopy (SEM-EDX) using electron microscopy and energy-dispersive x-rays to determine the alloy composition. The predominant metal is copper, followed by zinc. There are also small percentages of manganese and nickel. PCGS and NGC have both authenticated and certified these 1999
State Quarters as being struck on experimental planchets.
Good luck

That's why I posted this list.
