Best Practices

Always record catalog numbers:
  • Scott - North American standard
  • Stanley Gibbons - British Commonwealth
  • Michel - European standard
  • Specialized catalogs - For specific countries
Why: Catalog numbers are essential for identification, valuation, and communication with other collectors
Be honest about condition:
  • Use standard grading terminology
  • Note any faults (thins, tears, creases)
  • Describe centering accurately
  • Note gum condition for mint stamps
  • Consider third-party certification for valuable stamps
Overgrading damages your credibility and can affect insurance claims
Protect your collection:
  • Use acid-free mounts and albums
  • Control temperature and humidity
  • Avoid direct sunlight
  • Handle with stamp tongs (never fingers)
  • Use glassine envelopes for storage
  • Store vertically to prevent damage
Optimal conditions:
  • Temperature: 65-70°F (18-21°C)
  • Humidity: 45-55% RH
Create high-quality scans:
  • Scan at 300-600 DPI minimum
  • Include both front and back
  • Show perforations clearly
  • Capture any varieties or flaws
  • Use consistent lighting
Good images are essential for insurance, sales, and authentication
For valuable stamps, consider:
  • PSE (Philatelic Stamp Expertise) - Grading and authentication
  • PF (Philatelic Foundation) - Expert opinions
  • APS (American Philatelic Society) - Expert service
  • BPA (British Philatelic Association) - UK expert committee
When to certify:
  • Valuable stamps ($500+)
  • Errors and varieties
  • Controversial items
  • Items for sale
Document ownership history:
  • Auction records
  • Dealer purchases
  • Previous owners if known
  • Exhibition history
  • Published references
Why: Provenance can add value, especially for famous rarities
Use Storehouses collections to organize:
  • By country: “United States”, “Great Britain”
  • By era: “Classic US (1847-1893)”, “Modern Commemoratives”
  • By topic: “Space Exploration”, “Wildlife”
  • By format: “Plate Blocks”, “First Day Covers”
  • By value: “Key Pieces”, “Investment Grade”

Common Questions

Identification steps:
  1. Determine the country (look for inscriptions)
  2. Find the denomination
  3. Note the design/subject
  4. Check the perforations
  5. Look up in Scott or appropriate catalog
Helpful resources:
  • Scott Standard Postage Stamp Catalogue
  • Online identification forums
  • Dealer expertise
  • Collector clubs
It depends:
  • Modern stamps (post-1930): MNH almost always more valuable
  • Classic stamps (pre-1900): Used examples may be more affordable, some useds are scarcer
  • Rare stamps: Either condition can be valuable
  • Errors: Mint typically preferred, but used examples of rare errors still valuable
Collect what you enjoy - both mint and used have their appeal
Warning signs:
  • Price too good to be true
  • Poor quality paper or printing
  • Incorrect perforations
  • Suspicious gum
  • Missing or incorrect watermark
  • No provenance for rarities
Protection:
  • Buy from reputable dealers
  • Get certificates for expensive stamps
  • Study genuine examples
  • Join collector organizations
  • Consult experts when in doubt
Generally, no:
  • Amateur cleaning can damage stamps
  • Removing cancels destroys value
  • Improper soaking damages gum
  • Leave restoration to professionals
Safe practices:
  • Light dusting with soft brush only
  • Professional conservation for valuable items
Valuation methods:
  1. Catalog value: Reference point, not market price
  2. Auction results: Actual realized prices
  3. Dealer prices: Retail and wholesale
  4. Online sales: eBay, HipStamp, Delcampe
Important notes:
  • Catalog value ≠ market value
  • Condition dramatically affects price
  • Common stamps sell below catalog
  • Key stamps may exceed catalog
