This type of stuff happened quite a bit as this is the way most composite photos were created.
Composite photos are not considered type 1s according to the Yee/Fogel system adopted by PSA. Prints created around the time the negative was created would be considered type 3s. Newer prints would be type 4s.

TO answer your questions..
1 and 2) As others have said, I would scan the negative and use that if I was going to make prints.
3) I am not aware of PSA encapsulating negatives. They would encapsulate prints made from the negative as type 4s I would imagine.
4) I find negatives hard to price. Some, I thought would be expensive sold cheaply and others shot to the moon. For a generic Musial, I would not expect more than a couple hundred. Maybe a rookie image would bring more. How much, I am not sure.

IF YOU DO SCAN it and use to make a Good Print. Please take a picture and post it. Would love to see how it comes and how the quality looks
