1808 bust half found on Harriet Tubman home site

I don’t subscribe to The NY Times to read the article but this is what’s being reported. There are pictures of the coin and I find it surprising. For one the coin looks to have very little if no environmental damage for being in the ground 200 years. I’m an novice so comments are most welcome.

For at least two decades, historians had been searching for the site of the cabin in which Harriet Tubman lived with her family as a young adult.
“Land records told us it was here somewhere,” said Julie M. Schablitsky, the chief archaeologist at the Maryland Department of Transportation State Highway Administration, who led an excavation of the swampy terrain on Maryland’s Eastern Shore beginning last fall. “We couldn’t understand why we weren’t finding anything. It was like, ‘Where is this place?’”
Then, on a whim, Schablitsky swept a metal detector along the side of an abandoned road, closer to the river. And she found a coin from 1808 — the same year that Tubman’s parents, Ben Ross and Harriet Green, known as Rit, were married. And, not far away, she found ceramic shards that dated to the 1820s to 1840s.
It was then that she knew: She had located the cabin of Benjamin Ross, the father of Harriet Tubman, the Underground Railroad conductor. She had lived there roughly between the ages of 17 and 22, from 1839 to 1844.
Kind of dark for a silver md find. My silver coin finds always came out of the ground bright.
That area of Southern Maryland the soil is very acid base... thus the coin color. I live not far from the area...as well grew up on the Chesapeake bay. The area is also very swampy ,again ive hunted,and fished the area many times.
One would be surprised as to how much history there is in this area. Dr. Mudd house , as well many old plantations and farms.
If you never been to Maryland....well plant a lot more than a week.....in fact plan a few years, as I would venture to say if you picked 1 place to see or visit here a day for 3 years you might be able to see most attractions. No kidding.... Kent Island founded 1604 ,Annapolis, Baltimore, Fredrick, those 4 alone will keep your schedule full for a couple years.
Oh not only was Annapolis was once the capital of the united states, but the first treasury sits on our state house lawn. George Washington resigned as the leader of the continental army in the state house..... Church Circle has members of the Royal family burried there......Like I said so much to see and do.... we really are America in minature.

Very little environmental damage occurs in this area?

Any silver coin that has been in the ground for a long time will have countless fine hairline scratches running in all directions. They are a result of the coin surface's contact with the silica, an abrasive, in the soil.The hairlines are easy to see with a low magnification power inspection glass.
