Vintage negatives value and ok to print it?

[chalupacollects]

Hello everyone,

Hope someone can help!

For now I wish to keep the player under wraps until I can figure out my next steps...

I have obtained a black/white photo negative of a major hall of famer of which said negative was used as the basis for his rookie card.

First question is: Is it wise to have some prints made up off of it?

Second questions: Will printing copies damage the negative or is ther an alternative process?

Third question: If I remember right doesn't PSA and JSA encapsulate these?

Lastly - What would these generally be valued at?

Thanks in advance!!!
