Yep, certainly worth more than $200, but how much more would depend on a lot of things. From the photos it looks like it may have been refinished (color of metalwork & buffed-off lettering on barrel, etc.) sometime in it's past, if so that would detract from its value, also the bore condition would have some bearing especially if it was being purchased as a shooter. I bought a similar style musket a few years ago (Bavarian-made Amberg M.1858) in well used but solid original condition, with a good bore, which I paid $595 for. I'd put a ballpark figure of $400-$800 on yours. If it's untouched with a good bore, probably as much as $1200.
