I have seen a listing on e-bay in which one had a bid of $127 that ended on Sept. 19th without meeting the reserve of $140.
I dug a cannonball out of the ground ...im wondering what it is worth ?
A cricket ball weighs between 156 and 163 grams or about six or seven ounces. Most cannonballs weigh several pounds. Some cannon fire 20 to 30 pound balls.
The concept of the gauge originated with pistols, and later shotguns. The gauge described the size of the barrel by the fraction of a pound of a round iron ball that just fits the barrel. For example, a 12 guage shotgun has a barrel that will just fit a round iron ball that is one twelfth of a pound. This measurement stemmed from cannon measurements, which measured the cannon by the size of the cannon ball it fired (such as a 6 pound cannon, or 20 pound cannon). There are different gauges that describe thickness, including the American Wire Gauge that measures the thickness (diameter) of electrical wire, US Steel Wire Gauge for steel wire, Sheet Metal Gauge, etc.
