How to Identify Authentic Stamps & Postal

Before investing in or valuing stamps & postal, check these key indicators:

• Maker's marks and labels — check the bottom, back, underside, and inside for stamps, signatures, or paper labels
• Materials and construction — premium materials and hand-crafted construction indicate higher quality and value
• Period-appropriate features — design elements, hardware, and techniques should match the claimed era
• Condition assessment — note any damage, repairs, or modifications that affect value

Common Mistakes in Stamps & Postal Valuation

• Relying on style alone — a piece that *looks* old may be a reproduction. Always check construction and marks.
• Ignoring condition — damage can reduce value by 50% or more, even for desirable items
• Overvaluing without attribution — unmarked pieces are almost always worth significantly less than attributed ones
• Assuming all old items appreciate — market tastes change. Some subcategories are declining while others are rising.
