One way, and the simplest, is to look on the barrel , if the weapon says"BlackPowder Only", it is not an original.
Otherwise the blue book of muzzleloader values is a good place to start.
I'm thinking that you are looking for antique cannons that fire shotgun size rounds and that load from the "Breach" or back instead of the front or "Muzzle".

The value of any "Antique" is always a very subjective opinion. research what a similar item has sold for and you will have your answer.
Your question answers itself, "muzzle loader". You load it from the muzzle. Actually, that's incorrect. They use the term "muzzle loader" improperly. It's a bolt action black powder rifle. The powder is pre-pressed into slugs that you load into the chamber, along with wadding and a bullet. I would guess you could load it down the muzzle, but it's faster and easier to buy the slugs and load that way.
