Collection Value EstimateFormula
Total value ≈ Σ (catalog value × condition factor × quantity) for each catalog entry.
Condition AbbreviationsStandard
Mint NH (never hinged), Mint H (hinged), FU (fine used), VF (very fine), XF (extremely fine).
Batch Scanning
Scan album pages in batches of 20 stamps — faster than individual scans for used material.
Consistent Grading
Define your condition standards in writing — personal grading drift causes valuation errors.
Digital Backup
Catalog data without image backup is incomplete — disk failure loses years of work.
Safety Notes
- Store digital catalog backups separately from physical collection — fire or theft can take both otherwise.
- Do not include purchase prices in publicly shared catalog exports — reveals collection value.
