U Number Security Machins U2911 - U3039

U/M = Unmounted Mint

VFU = Very Fine Use

Any self-adhesive VFU U-Security will be provided on-piece, and does not include the backing paper mentioned on the listing. Regular gummed stamps will be removed from the envelope.

Re. Backing Paper; where specified singularly as "Plain", "Inverted", "Up", "PB-sL" or "PB-Ls", this means that the given stamp was only issued with that backing paper type. Where multiple variants are stated e.g. "Type PB-Ls/sL", this means that the stamp was printed with both of these backing types possible, and that a random choice will be provided.
