If you want to grade Iraqi dinar and Iranian rial notes consistently, you need standardized criteria—not guesswork. Professional grading relies on four observable factors: paper integrity, corner sharpness, crease presence, and ink retention. This guide breaks down UNC, XF, and VF tiers with actionable checkpoints so you can assess any Middle Eastern banknote with confidence.
Official Grading Tiers Explained
UNC (Uncirculated)
Zero handling marks. Paper retains original factory stiffness. Corners are razor-sharp. Intaglio printing is fully tactile. No center folds, edge wear, or surface abrasion.
XF (Extra Fine)
One light center fold maximum. Paper remains crisp with minimal softening. Corners show slight rounding. Ink density intact. No tears, stains, or pinholes.
VF (Very Fine)
Multiple soft folds visible. Noticeable edge wear and corner blunting. Paper flexibility reduced. Minor surface scuffing acceptable. Major design elements remain clear.
Step-by-Step Verification Checklist
- Light Test: Hold the note against a bright, neutral light source. Verify watermark clarity and check for hidden creases or repairs.
- Tactile Check: Run a clean fingertip across portraits and large numerals. Genuine intaglio printing produces distinct raised ridges.
- Corner Inspection: Examine all four corners at eye level. UNC notes show zero compression; XF allows minor blunting; VF shows visible wear.
- Edge & Margin Scan: Look for trimming, uneven cuts, or adhesive residue. Authentic banknotes maintain uniform white borders.
- Serial Number Audit: Digits should be evenly spaced, sharply printed, and aligned. Smudging or doubling indicates circulation stress.
Common Grading Mistakes to Avoid
- Mistaking a pressed or ironed note for UNC. Paper compression permanently alters fiber stiffness.
- Ignoring watermark ghosting. Faded or doubled watermarks indicate improper storage or environmental damage.
- Grading by photo alone. Screen calibration and lighting angles distort paper texture and fold visibility.
- Confusing circulation wear with printing defects. Misaligned registration is a factory error, not a grading fault.
For standardized reference protocols, consult the International Bank Note Society (IBNS) grading guidelines.
Storage & Handling for Accurate Long-Term Grading
Condition degrades through improper storage, not time. Maintain grading accuracy by following these protocols:
- Use inert Mylar or polypropylene sleeves. PVC sleeves off-gas chemicals that yellow paper over time.
- Store notes flat in modular binders. Vertical stacking creates pressure marks on lower pieces.
- Maintain 40–50% relative humidity. Extreme dryness causes brittleness; excess moisture promotes warping.
- Handle with clean, dry hands or cotton gloves. Skin oils accelerate ink fading and surface staining.
Consistent grading requires practice, proper lighting, and reference to official Central Bank of Iran (CBI) and Central Bank of Iraq (CBI) specifications. For cross-referenced catalog data and Pick number verification, visit Banknote Book before finalizing any acquisition.
