That sounds like a good question for a search engine's AI such as Google's:
"Mint Never Hinged (MNH) is a philatelic term for a postage stamp that is in perfect, pristine condition. It means the stamp is completely unused, has never been stuck into a stamp album, and retains its full, undisturbed, original post-office gum on the back.
Why It Matters to Collectors
Historically, collectors used small, semi-transparent pieces of folded paper (called "stamp hinges") to stick their stamps onto album pages. When these hinges were removed, they often left behind sticky marks, disturbed the gum, or tore the paper.
Mint Never Hinged stamps are highly sought after because they represent the exact state the stamp was in when originally purchased from the post office. Because they are scarce and in flawless condition, MNH stamps usually command a significant premium over hinged stamps."
