Did you know?… There are several kinds of errors on Wyoming quarters that relatively few people know about.

These error coins are worth a significant sum of money.

See how much Wyoming quarters are worth today  + 5 valuable Wyoming error quarters you can find in pocket change!

If you know what to look for, you could score big by finding a scarce and valuable Wyoming state quarter error in your pocket change!

In 2007, the Wyoming quarter was released as part of the 50 State Quarters program — which spanned from 1999 through 2008 and became one of the most popular and ambitious commemorative coin programs the United States Mint ever released.

Some 50 State Quarters were made with errors or varieties, and among these are the Wyoming quarters.

It’s time to start searching through your loose change and bank rolls of quarters for some fun error coins!

Following is a list of the Wyoming state quarter errors you should be looking for and what they’re worth if you find one.

How Much Are Wyoming State Quarters With Errors Worth?

Here’s a list of the most popular 2007 Wyoming quarter errors & varieties… and what they’re worth today.

#1 – Wyoming Quarter With Doubled Die Error

Some of the 2007-P Wyoming quarters made at the Philadelphia Mint were struck with a doubled die reverse that shows some minor doubling around the saddle. Values for this doubled die coin range from $3 to $7.

#2 – Wyoming Quarter Pooping Horse Error

A little gross, maybe, but there’s an interesting die break on some 2007 Wyoming quarters between the rear of the horse and its tail that makes it look as though the horse is doing its business. (Yep… Really does look like that!) It’s just a die break — but an unfortunate one. Wyoming quarters with this strange die break (some calling it the “pooping horse error”) are worth $15 to $25.

#3 – Wyoming Quarter With Die Break Through Date Error

There’s also a really peculiar die break that shows a long, crooked line from the tip of the horse’s front hoof all the way through both zeros (“00”) in the date, the “S” of “PLURIBUS,” up to the coin’s rim. Examples of this 2007 Wyoming error coin normally sell for between $3 and $10, depending on the coin’s condition.

#4 – Wyoming Quarter With Die Cuds Error

Some collectors have found what appear to be die cuds (die breaks hanging off parts of the design) on 2007 Wyoming quarters. Values for these coins range are based on the size of the cud and condition of the coin. These error coins are generally worth $2 to $5.

#5 – Other 2007 Wyoming Quarter Errors

There are other types of errors you should be looking for on Wyoming quarters, too.

These types of errors can actually be found on any coin and aren’t particular to the Wyoming state quarter alone.

Still, these are some neat errors that are worth a pretty penny and should be on your search list:

Even if you can’t seem to find any of the 2007 Wyoming state quarter errors right away, don’t give up. They’re out there!

You may not hear much about these particular error quarters, and they’re not necessarily worth a ton of money right now — but these error coins are still worth looking for.

    I have an error on a Wyoming quarter but I haven’t found one like it to be able to put a price for the error. The T in equality has extra Silver to make it messed up

      Hi, James —

      Would you please zoom in on the area of the suspected doubled die? I’m not seeming to find it in this pan shot. Along with a close up of the doubled die itself, would you please also upload a closer image of the obverse/front?

      Thank you,
      Josh
