These 2 1999P quarters are at first very similar.
However, the drop test reveals that they are made of different metals.
I have no idea. However, maybe one of them is a fake, maybe from PRoC????
OR were these made of a different metal, perhaps test coins?
The drop test had two very different sounds.
any help is appreciated.
These coins belong to a friend
Thank you all for your input.

Exposure to high heat will change the internal structure of the metal, relieving the internal stresses, and change the tonal qualities. So I think the top coin was heated to close to its melting point.
The photos seemed to have flipped since I first saw the post. But, I agree with @dcarr , heat is the reason. So, now looking the bottom coin (the one that looks like there is a break at 3-4k), is heat damaged.
It appears to me the bottom coin suffered damage from a heat source.

Thank you to all for your input, we never thought about heat.
first, the original post had the weight shown in a weight measure other than grams. posted now is in grams.
even if the coin was subjected to high heat, would that so drastically change the weight and the metal properties?
is there any value to any of these two coins?

I hadn't noticed the weights before now.
There is also a possibility that the suspect coin is a home-made casting.
Does it look like there was ever a sprue attached to the edge of it ?

I'm not a tree hugger but in this case..........Ya just gotta do it.
The details remind me of our initial tree when I was a young buck.
On suspect clad coins the edge is an important factor. Are you able to get photos?
There is no hugging of the Charter Oak. It is one of the subjects on the state coins that met it's demise after appearing on the coins. New Hampshire's "Old Man of the Mountain" is another.
Not sure if your childhood tree still exists. Maybe it's petrified?
I don't know about the tree but the land owner could have been with all these kids in their tree with knives.
Come to think of it, we raked that tree's leaves every season. Anyway...
So the second coin is fake ? (which is the coin I was referring to and sry if that was not clear)
Thinking back, I sure was a tree hugger then. One slip up....... was a long way down.
I was too far away to hear the sound when you dropped the coins. Can you drop them again? I'm closer to my phone now.😆
A mass loss of over a gram, for a coin that only weighs less than 6 grams, "heat" alone cannot explain - you need to explain where the missing mass went; neither copper nor nickel simply evaporate without melting the coin completely.
If it's a genuine coin, the better explanation for mass loss is "acid damage" or similar corrosion, which explains both the appearance and missing mass. However, again the edge view would be telling, if you get the "oreo-like" appearance of the edge where acid has attacked the copper core more readily than the clad layers, acid would be confirmed. But acid alone cannot explain all the features seen here.
The other option, counterfeiting, also cannot be ruled out.

Apparently I have been awarded one DPOTD.
Looks like a deep strike thru or tooled gouged on the obv filled with solder to me, in addition to quite a bit of wear, whether sanded or polished. The details are flattened on the obverse significantly. It appears environmental damage or exposure to a caustic material is also responsible for the pitting and missing material. Fifteen years of abuse somewhere.
The bottom coin appears to have lost weight, possibly due to acid or salt water. If it is real, then the lost weight will give it a higher "ping" than the standard quarter. I encounter these occasionally in my CRHing, and have done weight and sound tests on more than a few. This seems to be the likely reason for the higher, almost "silverish" noise.

Connecticut's Charter Oak was blown down in a storm in 1856. I realize the State Quarter series went on for a long time, but not that long!

Good to know. Thanks for the correction. I'll have to amend my trivia arsenal.
At least the Old Man of the Mountain in NH collapsed after it appeared on the state quarter. Of that I'm (pretty) sure.
Thank you all so far
Here are the rim images. Hopefully this will help.

Yes, the images confirm that it is counterfeit.
"Hold the fort."! ?......
I have here 2 coins (for now) with that same, tree trunk or wet cement look with that unguided penmanship look.
My question is, "This style or look has a rap sheet"? Or, just a brother from a different mother ?
Bytheway @YQQ where you been ? Everything cool ? Watch this ?
When was the war of 1812 ?
where have I been???
well, since 1966 in Canada...
It seems that the subject coin might be a forgery? or not?? what is the concensus ?
But why this one 1999 ? and why are there not more known as fakes?
It seems a lot of work for just one item?
I originally posted a very nice one together with the subject coin
Is there any realistic value to it? and perhaps a suggested grade?
If you bring a clad coin to its melting temperature then stop the coin will show blisters. Trust me I have buckets full of them. So I don’t think it was heat. Nor will heat add or subtract weight from the coin. If so, where did it go? I’ve gotta believe one of them is a counterfeit.
Would anyone recognize it as a CF?
If so. how ? what are the markers?
