Discovered this odd, dished-in area with a pattern of rays on the obverse of a 2016 NH State Park Quarter.

Did this happen when it was made? Or after?

How does a worn die result in a SUNKEN area in the coin?

I thought Die Deterioration was when part of the die wears away, resulting in a RAISED area on a coin in a part that's usually flat, and in details on the coin that are more shallow (because the surrounding area is raised more than usual)?

I don't understand...

I studied the page on Die Deterioration, but I don't see how that would result in this sunken area between the red lines:

Can anyone explain more, please?

Here are two pictures where the light shows the area is sunk in rather than raised:

This is VLDS as stated above. You don't see it so much in quarters compared to nickels.

The raised areas on the fields are called die flow lines. Looks like the die is almost time to be retired. They may try to rescue it, or retire it. (but now it is still being used. they figure no one will notice this?) We see it!

I'm still not sure how the sunk-in area happens, but at least I know what it is now. Thank you!

As the die strikes the planchet with 50 tons of pressure, the resulting kinetic energy release travels laterally across the face of the die, originating from its center.

This energy causes a minute amount of distortion to the metal of the die that builds up over time and can cause almost a "wave" of distorted metal on the die which results in a variety of effects, including the one you have here.

Distortion that moves from the center of the coin outward in a radial fashion is a key diagnostic for Die Deterioration.

Look up " Ridge Ring" on the zinc Lincoln cents and you'll see a similar phenomena also caused by the deterioration of the die.

Thank you!! That makes more sense. And I have found a handful of bright, crisp pennies with what looked like an extra rim at the bottom - now I know what caused that, too!

Coins are a deep subject, but different die events/varieties can make them different. Most coins are not variety coins. But when you find one, then it takes effort to identify which die it was from. The more you train your eyes, the more you will find or reject as being common or valuable. Just like at the beach, every grain is common, but gold is what you are looking for. That is not common. When you find it, what will tell you what it is? Your eyes. So train to know what to look for.
