Stamp Grading Explained: VF, XF, and Superb Conditions

Understand stamp grading terminology and how condition affects value. Learn what VF, XF, Superb, and other grades mean for your collection.

StampSnap Team

Stamp grading is the standardized system collectors and dealers use to describe a stamp's condition. Understanding these grades is essential for buying, selling, and insuring your collection. A stamp's grade can mean the difference between a $10 stamp and a $1,000 stamp of the same issue.

Why Grading Matters

The same stamp can vary dramatically in price based on condition:

| Grade | Relative Value |

|-------|---------------|

| Poor | 5-10% of catalog |

| Good | 15-25% of catalog |

| Fine | 40-60% of catalog |

| Very Fine | 80-100% of catalog |

| Extremely Fine | 150-200% of catalog |

| Superb | 300-500%+ of catalog |

A stamp listed at $100 in VF condition might sell for $500+ if graded Superb, or just $20 if only Good.

The Major Grading Factors

1. Centering

Centering refers to how well the stamp design is positioned within the perforations or margins. This is often the most important factor in grading.

Perfect Centering: Design is exactly centered with equal margins on all sides

Off-Center: Design shifts toward one or more edges

Jumbo Margins: Unusually large margins (can add premium)

2. Gum Condition (Mint Stamps)

For unused stamps, the original gum condition significantly affects grade and value:

Original Gum (OG): Stamp has its original adhesive

Never Hinged (NH/MNH): Original gum with no hinge marks

Lightly Hinged (LH): Small hinge mark, minimal disturbance

Heavily Hinged (HH): Obvious hinge remnants or disturbance

No Gum (NG): Gum removed or never applied

Regummed: New gum applied (significantly reduces value)

3. Freshness

Refers to the vibrancy of colors and overall appearance:

  • Fresh colors command premiums
  • Oxidized or faded colors reduce grade
  • Soiled or stained stamps grade lower

4. Perforations

The condition and completeness of perforations:

  • All perforations should be intact
  • Short or pulled perfs reduce grade
  • Blind perfs (incompletely punched) affect grade
  • Straight edges (missing one row of perfs) reduce value

5. Faults

Any damage affects grading:

  • Thins (paper loss on back)
  • Tears or cuts
  • Creases
  • Stains or foxing
  • Pinholes
  • Surface scrapes

Standard Grade Definitions

Superb (S)

The highest grade, representing near-perfect stamps:

  • Perfectly centered (equal margins all around)
  • Pristine condition with no faults
  • Fresh, bright colors
  • Full original gum, never hinged (for mint)
  • Perfect perforations
  • Extremely rare - less than 1% of stamps qualify

Extremely Fine (XF)

Outstanding stamps just below perfection:

  • Nearly perfect centering (within 5% of perfect)
  • No visible faults
  • Fresh appearance
  • Full OG, NH or very lightly hinged
  • Complete, even perforations
  • Perhaps 5% of stamps reach this grade

Very Fine (VF)

The standard "nice" stamp that most collectors seek:

  • Well-centered (design noticeably centered but not perfect)
  • No major faults
  • Good color and freshness
  • Original gum present (may be hinged)
  • Perforations clear of design
  • The benchmark grade for catalog values

Fine-Very Fine (F-VF)

Between Fine and Very Fine:

  • Slightly better than Fine centering
  • Minor imperfections acceptable
  • Sound stamp overall

Fine (F)

Average stamp in acceptable condition:

  • Noticeable off-center, but design complete
  • Perforations may touch design slightly
  • May have minor faults
  • Original gum may be disturbed

Very Good (VG)

Below average but still collectible:

  • Clearly off-center
  • Perforations may cut into design
  • More obvious faults acceptable
  • Gum may be heavily hinged or disturbed

Good (G)

Poor centering, possible faults:

  • Significantly off-center
  • Design may be cut by perforations
  • Various faults present
  • Space filler quality

Poor/Average (P/Avg)

Lowest grade, usually damaged:

  • Severe centering problems
  • Significant faults
  • Heavy damage
  • Value mainly as reference or space filler

Gum Grading Terminology

Never Hinged Grades

NH or MNH (Mint Never Hinged)

  • Original gum completely intact
  • No trace of any mounting
  • Post-1920 standard for premium stamps

OG/NH

  • Original gum, never hinged
  • Same as above, different notation

Hinged Grades

VLH (Very Lightly Hinged)

  • Barely visible hinge mark
  • Gum minimally disturbed

LH (Lightly Hinged)

  • Small hinge remnant or mark
  • Most gum intact

HR (Hinge Remnant)

  • Part of hinge still attached
  • Gum disturbed around hinge

HH (Heavily Hinged)

  • Large hinge marks
  • Significant gum disturbance

DG (Disturbed Gum)

  • Gum has problems beyond hinging
  • May be toned, cracked, or tropicalized

Grading Used Stamps

Used stamps are graded similarly but with different considerations:

Cancel Quality

  • Light cancel preferred
  • Cancel shouldn't obscure design
  • Neat, dated cancels may add value
  • Heavy or smeared cancels reduce grade

Cancel Types

  • Manuscript cancels (pen marks)
  • Circular date stamps (CDS) - often preferred
  • Machine cancels
  • Fancy cancels - can add premium

How to Grade Your Own Stamps

Equipment Needed

  • Perforation gauge
  • 10x magnifying glass
  • Watermark detector
  • Good lighting
  • Reference images for comparison

Step-by-Step Process

  1. **Check for faults first** - Use magnification to examine front, back, and edges
  2. **Assess centering** - Compare margins on all four sides
  3. **Examine gum** (mint stamps) - Look for hinge marks under good light
  4. **Check perforations** - Count teeth, look for short or pulled perfs
  5. **Evaluate freshness** - Compare colors to known examples
  6. **Assign preliminary grade** - Be conservative
  7. **Compare to reference images** - Use grading guides

Common Grading Mistakes

Over-grading Your Own Stamps

  • Everyone thinks their stamps are better than average
  • Be objective and conservative
  • When in doubt, grade lower

Ignoring Hidden Faults

  • Always check backs for thins
  • Look for repairs or alterations
  • Examine under different lighting

Misunderstanding Terms

  • "Original gum" doesn't mean "never hinged"
  • "Fine" doesn't mean "excellent"
  • Learn standard definitions

Conclusion

Understanding stamp grading is fundamental to successful collecting. Grades directly impact value and desirability. Take time to learn the terminology, practice grading inexpensive stamps, and consider professional grading for valuable items.

Remember that grading has some subjectivity - two experts might disagree by one grade level. The key is consistency and understanding what each grade represents. With practice, you'll develop an eye for quality that serves you well throughout your collecting journey.
