I recently got these off of auction. While I was only interested in the Cambodian note, the Congo notes are very cool to see in person.
For those more experienced than I, would it be worth it to try and unmount these notes? Should I try and find a professional or is this something I can do on my own with little risk of damaging the notes? If I do unmount them, I would intend to submit them for grading. Another question, would these be considered proofs? When I was originally bidding, I thought I was bidding on 3 notes that had been previously mounted. (Not 6 mounted notes, where only one side was printed).
