Antique Maps Value: How to Identify Original Old Maps

Antique maps are both historical documents and decorative art. Original maps can be valuable — but reproductions are everywhere.

Original or reproduction?

• Printing method: early maps were printed from engraved copper plates or woodblocks. Under a magnifier, engraved lines are crisp and slightly raised. Modern reproductions show dot patterns.
• Plate mark: copper engraving leaves an impressed rectangle around the image.
• Paper: old laid paper shows fine parallel chain lines when held to light; some have watermarks.
• Coloring: hand-coloring (watercolor) may be original or added later; printed color looks uniform.
• Centerfolds: many atlas maps have a central fold where they were bound.

Identify the map

Check the title, cartographer or publisher, date and place of publication — usually in a cartouche (decorative panel) or margin. Many maps were issued in several editions or "states".

What affects value

• Cartographer and publisher
• Region: demand varies by area and collector base
• Age and rarity
• Decorative appeal: cartouches, sea monsters, ships, attractive coloring
• Condition: tears, foxing, trimmed margins, stains

Care

Keep maps flat, away from sunlight, in acid-free folders or mats. Don't tape repairs.

Value it
