That depends...
Early versions of the Kentucky Long-Rifle were flintlock guns and thus required flint to ignite the powder in the flash-pan.
Later versions were made to use percussion caps; while many of the older flintlocks were modified by gunsmiths and 'upgraded' to percussion caps.

More than likely your barrel will say .22 Long Rifle only. So, you can use any .22 Long Rifle ammunition.
We need the model.
Not from another US State of Territory as long as you are a US Citizen.
Anywhere from $25 to $5000. The value of ANY gun will be based on exact make, model, condition, and originality. The term "Kentucky Long Rifle" could cover anything from a modern, kit reproduction in fair condition, to an original, handmade in excellent condition. You will need to visit a gun shop and get a hands on assessment. Sorry, but your question is too broad for us to give you a real answer.
Nope. And you will need the MAKE of the rifle as well as model. Check with a gunsmith or gun shop.
There are dozens of different models of the Mossberg 22 rifle. You did not tell us which model, and we need that to give you an answer. Sorry.
