Auction houses employ a meticulous process to determine the starting bid for rare porcelain sculptures, balancing historical significance, market demand, and expert appraisal. Key factors include the piece's provenance, which traces its ownership history and authenticity, significantly influencing its value. Condition is another critical element; flawless pieces command higher starting bids, while repairs or damage may lower expectations.

Market trends and recent sales of comparable items also play a role, as auction houses analyze data to set competitive yet enticing opening prices. Additionally, the rarity of the sculpture—whether it’s a limited edition or a unique artifact—can dramatically impact the starting bid.

Finally, expert appraisers assess the artistic merit and cultural importance of the porcelain, ensuring the starting bid reflects its true worth. By combining these elements, auction houses aim to attract serious bidders while maximizing the final sale price.
