1999 experimental quarter with no copper in rim?

I found a 1999 p quarter with no copper in the edge of the coin, it does not appear to be plated. What do you guys think?

First picture is overexposed and super-blurry, others are shadowed and still blurry. Try propping it vertically between two books, so that the top of the rim is about even with the books. Take a picture of that, your camera will focus on the books, and the coin will be in focus too.

Having said all that, though:

a) Weight, to the nearest tenth (or better, hundredth) of a gram?

b) Marketers plated many, many thousands of these. If you can't see copper in the rim, it's almost certainly plated. Why do you say it doesn't appear to be? (You have a much clearer view of it than we do...)

 

Okay let me try that I’ll repost

 

It’s not shiny but rather dull

 

Is it possible it got struck on a Susan b Anthony planchet?

 

It looks like the Quarter has been plated.

 

At the edge there is a separation of metals but they are both nickel colored.

 

What’s weird is the quarter is very dull...

 

It looks like it had been plated to me.

The color of the rim doesn’t match the surface of the quarter either, or at I just imagining?

 

I still say it's plated.

 

I’ll update you with weight tomorrow

 

Do the experimental quarters have a different mass?

 

SBA Dollars minted at Philadelphia were Clad coins. You should be able to see the copper on the edge. (Outer layer of CN bonded to a inner core of pure copper). I vote for your coin being plated on a clad quarter planchet.

 

A couple close up, I guess I’m not seeing the signs of plating is all. The heritage auction page says there are four different kinds of experimental planchets, one with a green color and no copper core.

 

Would you be so kind as to post a link to Heritage where they explain that. I'd like to learn about them. Thank you.
I did find this: https://www.numismaticnews.net/ideas/experimental-planchets-used-for-state-quarters

I don't know how many the US Mint produced or what they did with the experimental coins but the odds of finding one in circulation, IMO would be astronomical. Be nice if your coin was one of them.
EDIT. Looking further I found this site. If you scroll down you'll see they claim only 15 State Quarter experimental planchets were struck. What are the odds that you have one? https://minterrornews.com/faq.html

 

Don’t stop believing https://coins.ha.com/itm/errors/199...arter-struck-on-an-experimental/a/308-10031.s

 

It was plated and circulated after that.

 

Believing? Believing what? Did you read this part? Are you color blind?

"The first type has the color of a Sacagawea Dollar and a copper center core. The second type has the color of the Sacagawea Dollar but does not have the copper center core. The third type has a slight green coloration and a copper center core. The fourth type has a slight green coloration but does not have the copper center core."
