I dug a cannonball out of the ground ...im wondering what it is worth ?
a cannon ball
The cannon (also called artillery or gun or field piece) has no acceleration. It's just a stationary tube; a gun barrel.The cannon ball (also called a shell or projectile) travels at a speed determined by it's propellent charge; interior of the gun tube (rifled or smoothbore); length of gun tube; and the caliber of the weapon (gun size).As a rule: Larger projectiles travel slower; rifled barrels shoot slower projectiles; shorter gun tube have shorter ranges; smaller powder charges (propellent) travel smaller distances.I'm sorry, but the cannon does accelerate in the opposite direction of the cannon ball. This is called recoil. Old cannons simply rolled backwards as a result of recoil and had to be manually pulled forward again and reaimed. Modern artillery pieces all use recoil absorbing mechanisms that permit the barrel to recoil without moving the carriage, then automatically reextend the barrel.To answer the original question, the cannon is heavier and the ball is lighter, therefor the ball accelerates faster than the cannon.
That depends on what is it made of, however even lead cannon ball would float in mercury, let alone steel one. If you compare densities, you can see that mercury is more dense than lead in room temperature (13530 kg m-3 vs 11 540 kg m-3). One can imagine a cannon ball made of depleted uranium perhaps, which would sink in mercury, being more dense.
With both projectiles round and made of the same heavy material (same densities), they'd get to the ground at the same time. Air resistance would be minimized this way. A ping pong ball cannot fall as fast as a cannon ball unless both are falling in a vacuum. Galileo put us straight on this phenomenon.
It has no value, if no one wants the ball. Value is based on want and need.

the size of the cannon ball depends on the size of the cannon. civil war cannons had cannon balls about the size of a child's head, aprox 30cm across

Yes, both have the same energy, but because cannon is heavier the cannon ball gets more momentum and thus greater velocity.
The cannon would want to move backwards with the same speed as the ball wants to move forward.
The first cannon ball was made in the 3rd century BC in a place called Alexandra
1.2 x 10^4 J That is in Significant Figures

the explosion of gunpowder behind it propells it out of the cannon.
