Selos: A Complete Guide to Identifying and CollectingCollecting postage stamps — known as philately — is a hobby that blends history, art, geography, and detective work. “Selos” (Portuguese for “stamps”) opens a window to the past and connects collectors across generations. This guide covers everything a collector needs: how to identify stamps, evaluate condition and value, organize a collection, avoid fakes, and grow your hobby responsibly.
What Are Selos?
A selo (plural: selos) is a small adhesive label issued by a postal authority to indicate prepayment of postage. Beyond their postal function, selos reflect national identity, commemorate events, display artwork, and document technology and culture. They vary widely in design, printing methods, paper types, perforations, and gum (the adhesive on the back).
Why Collect Selos?
- Education: Selos teach geography, history, politics, art, and technology.
- Aesthetic pleasure: Many stamps are miniature works of art.
- Investment: Some selos appreciate in value, though collecting should primarily be for enjoyment.
- Community: Philately has clubs, exhibitions, and online forums.
How to Identify a Selo
Identifying a selo means recording its country, date, denomination, design, and technical characteristics. Follow these steps:
- Read the design and inscriptions: Country name is usually obvious; denominations show value. Look for commemorative text or series titles.
- Note the date or context: Many stamps include a year or feature an event you can date.
- Examine printing details:
- Printing method: engraving (intaglio), lithography, offset, photogravure, or gravure. Engraved stamps have raised ink you can feel.
- Color variations: Different print runs can produce shade differences.
- Inspect paper and gum:
- Paper types include wove, laid, watermarked, and fluorescent papers.
- Watermarks help identify issues; use a watermark detector or fluid.
- Gum can be original, disturbed, or regummed—important for value.
- Check perforations: Measure perforation gauge (teeth per 2 cm). Imperforate stamps were issued historically or as special issues.
- Look for overprints or surcharges: Countries often overprint existing stock in emergencies or regime changes.
- Search catalogues and databases: Use stamp catalogs (Scott, Michel, Stanley Gibbons, Yvert et Tellier) or online databases for exact identification and numbering.
Tools Every Collector Should Have
- Tweezers (stamp tongs) — handle stamps without damaging them.
- Perforation gauge — measure perforations precisely.
- Magnifier (loupe) — inspect details and printing.
- Watermark detector/fluid — reveal hidden watermarks.
- Stockbooks, album pages, or glassine envelopes — safe storage.
- Hinges or mounts — mounts preserve gum; hinges were traditional but can reduce value.
- Reference catalogs — essential for identification and valuation.
Grading the Condition of a Selo
Condition drastically affects value. Key factors:
- Centering: How well the design is positioned within the margins. Well-centered stamps command higher prices.
- Gum: Original, undisturbed gum increases value. Unused with original gum is preferable to regummed or hinged.
- Perforations: Missing or repaired perforations reduce value.
- Paper quality: Tears, thins, creases, or stains lower grade.
- Cancels (postmarks): For used stamps, a light, legible cancellation that does not obscure the design is preferred.
- Color: Bright, unfaded colors are better.
Common grades: Mint never hinged (MNH), Mint hinged (MH), Very Fine (VF), Fine (F), Good (G), Poor (P).
Rarity and Value
Value depends on scarcity, demand, condition, and provenance. A few points:
- Limited print runs, printing errors, and early issues are often valuable.
- Famous rarities include stamps with printing errors, color inversions, or unique cancellations.
- Catalog values are guides; actual sale prices vary by market and condition.
- Provenance and certificate of authenticity from a reputable expertizing service add value for high-end items.
Detecting Fakes, Forgeries, and Repairs
- Compare suspected stamps to high-resolution images from catalogs or auction houses.
- Check paper and watermark consistency with known issues.
- Examine perforations and printing detail under magnification.
- Smell the gum (some forgeries use modern adhesives) and test for regumming with careful light inspection.
- Seek expertization certificates for high-value pieces. Reputable expertizing bodies include BPA (British Philatelic Association), PSE (Professional Stamp Experts), and national philatelic societies.
Building and Organizing Your Collection
Decide a collecting theme to stay focused. Common approaches:
- Country-based (all stamps from one country).
- Topical/thematic (birds, space, art, sports).
- Time period (classic stamps, modern issues).
- Error and variety collecting (misprints, color shifts).
- Postal history (covers, rates, cancellations).
Organize with a clear album system, labeling issues with catalog numbers, dates, and brief notes. Maintain a digital inventory (spreadsheet or specialized software) with photos and provenance details.
Buying and Selling Selos
Where to buy:
- Local stamp clubs and dealers.
- Stamp fairs and exhibitions.
- Online marketplaces (eBay, specialized auction houses, dealer websites).
- Estate sales and old letters/collections.
Tips:
- Start with reputable dealers for valuable purchases.
- Inspect in-hand when possible or request high-resolution photos.
- Beware of “too good to be true” prices for rare items.
Selling:
- Get items appraised and, for high-value stamps, obtain certificates.
- Consider consigning to auction houses for rare material.
- Use clear photos and detailed descriptions for online listings.
Caring for Your Selos
- Store in a cool, dry place away from sunlight.
- Avoid PVC-containing plastic sleeves (they damage stamps over time).
- Use archival-quality albums, mounts, and storage.
- Handle with tongs; avoid touching stamps directly.
- Keep stamps flat; avoid pressure that could crease or crush designs.
Joining the Philatelic Community
- Local clubs offer meetings, swap nights, and expert advice.
- National and international philatelic societies provide resources, journals, and exhibitions.
- Online forums, social media groups, and marketplaces connect collectors worldwide.
Advanced Topics
- Plate varieties, roulettes, tagging, phosphor bands, and coil stamps require specialized study and equipment.
- Postal history: study covers, rate changes, and routes for deeper historical insight.
- Specialized collecting: focus on proofs, essays, die proofs, and official stationery.
Final Tips for Beginners
- Start small: buy inexpensive lots to learn identification and grading.
- Educate before investing heavily; use catalogs and join a club.
- Enjoy the journey — stamps are as much about stories and discovery as value.
