Yep, though I just learned this myself:
“vf” stands for “very fine”; ”An attractive note, but with more evidence of handling and wear. May have several folds both vertically and horizontally. Paper may have minimal dirt, or possible colour smudging. Paper itself is still relatively crisp and floppy. There are no tears into the border area, although the edges do show slight wear. Corners also show wear but not full rounding.”
“unc” stands for “uncirculated”; ”A perfectly preserved note, never mishandled by the issuing authority, a bank teller, the public or a collector. Paper is clean and firm, without discoloration. Corners are sharp and square, without any evidence of rounding, folding or bending. No light handling is present, no compromise, a perfect note. An uncirculated note will have its original, natural sheen.”
