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