Civil war Cannon Ball?

[Smilodon]

Long story short, I had a few hours this morning to detect Downtown Charleston before they poured their new concrete driveway. I dug a few copper coins or flat buttons, they are totally encrusted. Then I found something silver that was in the shape of a heart, while I was retrieving it I could see a rounded edge that was iron in the side of that hole, I started to clear the dirt around it and I was pretty sure it was a cannon ball. Next I was worried if it had a fuse and could be dangerous. I could not see any fuses and it appeared to be solid. I slowly removed it, and I could tell by the weight it had to be solid. I have found many grape shots over the years but this thing is quite large. I put it on the scale and it looks to weigh around 12 - 14 lbs. Can anyone tell more for sure if it is indeed a civil war cannon ball and any other information would be awesome. Also what do I need to do to preserve it

We would need exact numbers of both weight and diameter to go any further. Looks like one though.

The One photo with the measuring tape is a bit hard to read but I just re-measured and it appears to be around 4.5", The scale photo shows ~ 13 lbs. Hope that helps.

Even if you find a case shot (exploding cannonball) after a century and a half in the ground it will be inert and not dangerous to remove from the soil. You are certainly in the right place to find artillery shot!!

Third and fifth pic look like it has a ridge around. If it has it's probably not a cannon ball. Fingers crossed i'm wrong.

Congratulations on your finds and accessing the area before it’s poured over with crete.

Rev war cannonballs had seams, and I think some confederate balls may have too. Charleston was also a hot spot in colonial times.

Mine found in Missouri has a seam. Verified to be bona-fide by qualified

I am thinking even slid shot will have a seam around it. I would soak in apple cider vinegar or use electrolysis to clean it up then wax it. Good luck.
Hopefully it is.

From the level of corrosion it may be Rev. War era. Maybe one of General Cornwallis's 12 pounders.
