What do you want to value?

Antique maps and globes are collected for their beauty, historical significance, and investment potential. A rare 16th-century world map can sell for $100,000-$1,000,000+, and even 18th-19th century maps regularly command $100-$10,000. Antique globes from notable makers like Rand McNally, Weber Costello, and Johnston are decorative collectibles worth $500-$10,000+. Many people find old maps tucked into books, framed on walls, or stored in drawers without realizing their potential value. Maps of early American territories, exploration routes, and city plans are particularly sought after. Understanding what you have prevents discarding or donating something valuable.
Understanding what drives the price of maps & globes helps you get the most accurate valuation.
Maps by renowned cartographers command premium prices. Early cartographers like Ortelius, Mercator, Blaeu, and Speed produced maps that are highly collected. Later publishers like Mitchell, Colton, and Johnson produced attractive maps that are more affordable but still valuable. The cartographer's reputation significantly influences value.
Older maps are generally more valuable, with 16th-17th century maps being the most sought after. Maps showing territories before they were fully explored or established have particular appeal. Maps predating major historical events (American Revolution, Civil War, Gold Rush) carry historical premiums.
Maps of certain regions are more valuable than others. Early American maps, maps showing California as an island, maps of Africa during the colonial period, and sea charts of major trade routes are highly collectible. City plans, battle maps, and maps showing specific historical events also have strong markets.
Original hand-coloring is more valuable than later coloring or uncolored examples. Clean, bright maps with strong impressions command premiums. Foxing (brown spots), tears, staining, and trimmed margins reduce value. Professionally conserved maps can recover some value, but original condition is always preferred.
Large wall maps and multi-sheet maps are more impressive and valuable than small page maps. Maps in original frames or bound in atlases retain context. Loose maps from disbound atlases are common in the market. Globe pairs (terrestrial and celestial) are more valuable than singles.
Get the most accurate valuation by following these tips when photographing your maps & globes.
Photograph the full map flat with even lighting, capturing all borders and text
Include close-ups of the cartouche (decorative title area) and any text identifying the maker
Show any damage, staining, foxing, or repairs in detail
For globes, photograph from multiple angles showing the overall condition and any maker labels
The antique map market is established and international, with specialized dealers and auction houses serving a knowledgeable collector base. Sotheby's, Christie's, and specialized map auctions by firms like Old World Auctions handle significant sales. The market for 16th-17th century maps remains strong, driven by their scarcity and artistic quality. American maps from the 18th-19th century are in steady demand, particularly maps showing the westward expansion. Decorative antique maps have a broader market among interior designers and casual buyers. The globe market has grown as these items have become popular decorative objects, pushing prices for quality antique globes upward. Digital mapping has not diminished interest in antique maps - if anything, appreciation for the artistry of hand-drawn cartography has grown.
Key indicators of value include: age (older is generally better), the cartographer's name, the region depicted, and whether it has original hand-coloring. Maps printed before 1800 are more likely to be valuable. Look for the publisher's name, date, and any text in the margins. Our AI can identify the map's origin, maker, and approximate value from photos.
Globe value depends on the maker, age, condition, and size. Globes from before 1900 are the most valuable, especially from makers like Newton, Betts, and Bardin. Size matters - floor-standing globes command higher prices than desk models. Condition is critical - torn, faded, or warped gores (the paper segments) reduce value significantly. Matching pairs of terrestrial and celestial globes are worth more than singles.
Look at the paper - original antique maps are on laid paper (with visible chain lines when held to light) or early wove paper. Modern reproductions use smooth, uniform paper. Original maps show printing impression (you can feel the indentation from the printing plate). Examine with a magnifying glass - original engravings show clean lines, while reproductions show dot patterns from photographic reproduction.
Specialized antique map dealers offer the most knowledgeable evaluation and fair prices. Online auction platforms like eBay work for mid-range maps. For high-value maps ($1,000+), specialty auction houses like Old World Auctions, Sotheby's, and Christie's provide access to serious collectors. Map fairs and antiquarian book fairs are also good venues. Always get multiple opinions on value before selling.
