Artisan signatures and maker's marks play a pivotal role in determining the value of porcelain sculptures, serving as a testament to authenticity, craftsmanship, and historical provenance. These identifiers, often discreetly placed on the base or back of a piece, can transform an ordinary ceramic work into a highly sought-after collectible.

For collectors and appraisers, a recognizable signature or mark from a renowned artisan or studio—such as Meissen, Sèvres, or Limoges—instantly elevates the piece's market value. These marks not only verify the creator but also provide insights into the era, technique, and rarity of the sculpture. For instance, early 18th-century Meissen porcelain bearing the crossed swords mark can fetch astronomical prices due to its historical significance.

Beyond prestige, maker's marks help trace the lineage of a piece, linking it to specific artistic movements or cultural moments. A missing or forged mark, conversely, can drastically reduce its value. Experts recommend cross-referencing marks with archival records to confirm legitimacy.

In today's market, even contemporary ceramic artists' signatures can significantly boost desirability, as collectors increasingly seek unique, handcrafted works over mass-produced items. Whether antique or modern, the presence of an authentic artisan signature remains a key factor in assessing a porcelain sculpture's worth.
