2003 Arkansas Experimental Quarter

I can take more pictures if you would like if so just ask and I will wish I could show you the color it's light like see threw very transparent I can explain it better than the camera shows that's the weird thing

You could be right but holding this coin is a different story the pictures you can't see this blue that I explain it's very different then toned coins iv seen it's a solid blue on the front even perfect on the sides and meet a copper on the side this coin weighs what a normal quarter weighs 5.6-5.7g it's just easier to explain or see with your eyes it really looks like a regular quarter in those pictures

Your coin looks to be number 1 in the list of Dirty Dozen Damages:

1) discoloration - stains from coffee, or environmental damage from being buried, heated, etc.
2) scrapes over much of the coin - damage from sliding on pavement, a parking lot coin
3) coin bent or edges not round - it has been smashed with a hammer
4) coin blank on all or most of one side - someone sanded it down
5) mirrored lettering - a vise job, a coin squeezed against another in a vise
6) rough, pebbly surfaces - coin that received an acid bath
7) smooth rims, smaller diameter - has been trapped rolling inside a dryer, a " Dryer Coin"
8) clear mounds on coin - glue that has dried transparently
9) small indentations in the shape of the letter D - marks left by the impact of the reeded edge of another coin
10) large blisters - coin exposed to high heat, such as in a campfire
11) shapes, often letters or numbers, not indented or raised - Pareidolia (like animal shapes in a cloud)
12) a circular scrape just inside the rim - " Ring of Death" caused by a coin rolling machine

Don't despair! Error coins remain ready to find from circulation, but they are outnumbered by unusual looking coins that merely have been damaged. If you can imagine a way to charge an undamaged coin into one like you see, that's probably exactly what happened to it. Changes to a coin after it leaves the mint's striking chamber are considered post mint damage, or PMD, and have no premium value.

Looks like Enviromental toning. Keep if you like but it is not an error or variety. Value 25¢

If I'm not mistaken, the experimental planchet State Quarters were only '99 & '00, so it doesn't make sense that your '03 would be one. I have to agree w/ the others, its most likely environmental staining/toning, but.... if it were my coin, I'd be curious as to the weight & see if it matches the chart coop supplied.

Yeh I weighed it it's 5.67grams
