Have to be weighed to get ASW.
While I have not yet weighed the dime, the quarter's weight is actually right on target (6.23 grams versus a standard weight of 6.22 grams)! Judging by the looks of the coin, I had thought it would weigh drastically less.

Severe ED probably corrosion from burial in a high salt environment, either on a beach, near the ocean, or in the ocean but in soil. The unusual pitting makes me suspect the coin was pressed up against wood. It was not conserved when removed, so the atmosphere reacted with the vulnerable metal and further ate it up.
That's what I thought as well: salt-water damage or exposure, or possibly the effects of a fire. But the question is, where would at least four massively different coins--spread out across at least 100 years--have successively circulated, and then gradually been dropped or lost?
The affected coins include the following (at least; there might be more): an 1891
Seated Liberty dime, an 1853
Seated Liberty quarter, a
Washington quarter, and a Stone Mountain Half-Dollar.
As someone else mentioned, what's truly odd is that the quarter, at least, does not appear to have suffered any weight loss. I'll check out the dime later and see how much it comes out to.

If the coin was "ate up" by salt water or acid of some sort wouldn't it weigh less than normal? The first coin the OP posted was near normal weight so the metal is all still there just moved around similar to a parking lot find.

Yes, it definitely should, since the metal would start leaching away or breaking down. The quarter was actually a tiny fraction overweight (6.23 grams versus 6.22), but I still have to see how much the dime weighs.
I mentioned this to someone else, but whatever affected this coin affected at least three other ones, all of which are quite different from each other: an 1891
Seated Liberty dime, an 1853
Seated Liberty quarter, a
Washington quarter, and a Stone Mountain Half-Dollar. They all exhibit nearly identical damage, which means that whatever accident or mishap affected the quarter and dime had to have impacted the rest of them too.
