It looks like a musket ball. Is it from a Spanish wreck? There is no way to tell. Round balls have been used for centuries by everyone. It could have been fired by anybody.

Your photo shows there is still a "crusty" layer of oxide-concretion on the lead ball. That makes estimating the ball's original diameter difficult. You say the ball currently measures .76-inch with the concretion on it. If, minus the concretion, the lead ball is about .71 to 72-inch, it is for a 1700s-to-early-1800s British .75-caliber musket, such as the famous "Brown Bess" musket. (The Mexican army had some of that kind during the Texas War For Independence.) If its diameter is .68 to .70-inch, it could be for a French, Prussian, Austrian, or Belgian .70 or .71 or .72-caliber musket. If it is .64 to .68-inch, it could be for a .69-caliber musket from Spain or the US or any of the other countries listed above. Unfortunately, without knowing the exact diameter of the lead ball under the concretion-layer, there are just too many possibilities for us to give you a specific ID for your shipwreck musketball.

Also unfortunately, removing all of the concretion-layer from the lead on two small spots on OPPOSITE sides of the ball is the only way to get an accurate measurement of its original diameter. If you want to risk doing that, we might be able to narrow down the musketball's ID. But as I said above, unless it turns out to be .71 to .72 diameter, there would still be a lot of possibilities.

the diameter taken where there's no concretion is 1,95 centimeter (sorry, I'm French), so I think it's 0,767 inches. Spanish silver coins had been found in the same area.
