✅ SOLVED Is this a small cannon ball?

[Hunter612]

I have this small heavy metal ball. I don't know if it is a cannon ball or not. Anybody know? Thanks for looking!

Your "Is it a cannonball?" question cannot be answered with certainty until you remove some rust-crust from opposite sides of the ball so you can accurately measure its diameter super-precisely with a Digital Caliper -- and also, weigh the ball on a Postal Shipping scale (not a household bathroom's weighing-scale) and tell us its precise weight in pounds and ounces. Then, we will compare the diameter & weight with the charts in the Artillery Ordnance Manual, to see if there's an exact match-up there with your ball's diameter and weight. www.civilwarartillery.com/shottables.htm (The Ordnance Manual's charts show the precise diameter and weight of artillery balls used in America from the Revolutionary War through the Civil War.)

What is the best way to get some of the rust off?

 

[TheCannonballGuy]

To do caliper measuring of an uncleaned dug iron ball, I use a hammer to gently tap the rust-crust off of some small spots on opposite sides of the ball.

It's best to measure a ball's diameter in at least three directions, because that how you tell if the ball is out-of-round. But seeing photo #3, which shows one side of your dug ball is already pretty clean, you can measure it in two directions (let's say, north-to-south and west-to-east) without having to do any encrustation removal. For the third measurement, clean a small spot directly opposite from the center of the clean side.

If you don't have access to a large-enough caliper (it jaws must fit across the ball), you can use what is called a Diameter-Tape. But the tape MUST be positioned exactly on the ball's "equator" to get accurate measurement. See one of Diameter-Tape in a photo (and info) here: http://www.pochefamily.org/books/SolidShotEssentialsMod.html

Precision weighing can also tell whether a ball is at least "possibly" a cannonball or not. For example, the Ordnance Manual specifies that a civil war 12-Pounder caliber Solid Shot cannonball should weigh 12.25 pounds (12 lb 4 oz). I should mention that it can also weigh an ounce or two less, due to casting-flaw bubbles inside the 19th-Century cast iron. But if a solid (not hollow) ball weighs right-at 12.0 pounds, it is a Sports Shot-Put ball (from the 12-pound Weight Class of that sport.) For fairness in Sports competition, the Sports Shot-Put balls are very carefully manufactured to always weigh exactly 12-pounds... because it is unfair if the other team's ball weighs 12.0 pounds and your team's ball even a little bit less than theirs.

So, the very first thing I'd do with your solid (not hollow) ball is weigh it on a Postal Shipping scale. If its weight is more than an ounce or two different from any Solid balls in the Ordnance Mnual's charts, it cannot be a cannonball.

For your sake, I hope it is a cannonball. Based on comparing its size with your hand in the photo, it MIGHT be a civil war 6-Pounder caliber Solid Shot cannonball, which was specified to be 3.58-inches in diamter and weigh 6.1 pounds (6 pounds 1.6 ounces).

Do you know if there was ever a battle involving the use of cannons anywhere near where you found that ball?

HMM it could be a ball for a ball mill, about the size for new balls.

I have no clue were it was found. I bought it at an estate auction. There was a lot of civil war artifacts at the auction. I just assumed it was a cannon ball. I paid $10 for it so if it isn't I won't take a big loss. I am going to try to measure it later. I am not going to be home for a few days so it may be awhile.

 

[Hunter612]

I measured the diameter as accurately as I could and I came up with 3.56 inches. I weighed it on a scale that was my grandpas and it was just a little less than 6.1 pounds. Not even an ounce less. It might be because there is a very small chunk out of it that is barely noticeable.

Those measurements match up within the "Tolerances" in the specifications in the Ordnance Manual for a civil war era 6-pounder caliber Solid Shot cannonball.

Do you know if there was ever a battle involving the use of cannons anywhere near where you found that ball? By "near" I mean with a few miles.)

Usually, when we relic hunters find an actual cannonball, there are other Military relics from the same time-period nearby.

By the way... with Solid-Shot balls, it's usually pretty difficult to tell which side in the war manufactured the ball. With "fuzed" (explosive) cannonballs, the fuze's form is an ID-clue about the ball's nationality. But, with solids, we lack that clue. Some people think the presence or absence of a casting-mold seam on the ball tells you whether it is a USA or CSA ball... but there's also a mold seam on MOST cannonballs from the Colonial era, and also on Mill-Balls from the Mining-&-Stonemilling industry.

I didn't find it. I bought it at an auction for $10 hoping it was a cannon ball. I am in tennessee so I would think it is from tennessee. It was consigned to the auction by a mans family and they said he was a treasure hunter but they didn't know where he got it. Would it be worth anything since I don't know where it came from?

It's unfortunate that that cannonball's heritage (the location where it was excavated) has been lost.

At the various civil war relic shows here in Virginia, an excavated 6-pounder Soild-Shot in "as dug" (uncleaned, rust-&-dirt-encrusted) condition sells for about $90-$100, unless it is badly corrosion-pitted. The same thing, after being cleaned by Electrolysis and coated with Satin-finish Polyurethane sealant, will sell for $125 to $150, depending on how smooth or how corrosion-pitted it is. That's the Retail price. The Wholesale price (what a dealer will pay for it) is of course less than the Retail price. You might be able to get a bit more than the Virginia price by selling it in a state where civil war cannonballs are less common than they are in Virginia.

Ok. Thanks for your help!
