Starting collecting muzzle loaders

[gvmforster]

Hi, I am just starting collecting a small way; I am more interested in shooting and building other than a few collected antique guns
I don' know if it is appropiate to ask for a ballpark value on guns here, but.....
one of my co-workers has 2 muzzle loaders he was given 30 years ago and he has no interest in them and offered them to me. Neither of us has any idea of value

One is a percussion "C. Robbins" in very rough shape, broken stock, etc; the lock is the best condition of the entire gun
the other is a "G Kopp" flintlock; in better condition, but alot of metal corrosin, esp. the lock.

Any advice will be most welcome
sorry I messed up adding pics

They look a bit like Bedford County Both are the desirable ' Sleepers' not got at so Ide expect there would be some good interest , if not my style .
Good Luck Rudyard

No info on value, but just looking at the pics with a bit of TLC they look as if you could breath fire back into them. Wonder what the one on the right was wrapped around bye the looks of the stock.
