Resale value depends on condition, materials, and included components. Dolls in pristine condition with minimal wear, intact skin texture, and full articulation fetch higher prices. Silicone generally commands stronger resale value than other materials when well maintained. Documentation matters: original packaging, care manuals, spare parts, and receipts reassure buyers about authenticity and upkeep. Cosmetic upgrades, such as new wigs or clothing, should be considered carefully, since excessive alterations can reduce value unless they are easily reversible. Keep dolls free from stains, tears, and discoloration; store them in stable environments away from direct sunlight and heat to prevent material degradation. Photographs from multiple angles, a detailed description of features, and clear notes about any defects will help establish trust with buyers. Consider market timing, as demand can fluctuate with trends and new releases. Pricing should reflect the doll’s age, condition, and market comps, yet remain fair to avoid deterring potential buyers. Finally, be transparent about any modifications or repairs performed, since honest disclosure protects both seller and buyer and sustains long-term resale value.
