Overall Assessment
A fascinating historical artifact showcasing the transition from personal autograph to industrial branding through the medium of the seal.
Authenticity Assessment

$50 - $200 USD (As a historical artifact; higher if provenance links it to a specific palace or imperial site).
Comparison to Known Examples
Consistent with 'Guan' (official) marks or artisan surnames found on Great Wall bricks or ancient city wall tiles.
Authentication Tips
Consult an expert in Chinese epigraphy or paleography to decipher the specific characters within the seal.
Certification Recommendation
Museum curatorial staff or academic departments specializing in Asian archaeology and ceramics.
Red Flags
No significant red flags observed; the wear patterns and calcification on the edges suggest genuine age.
Provenance Notes
Determine the geographical origin of the find, as site-specific context is more valuable than the mark itself.
Historical Context
These marks were often used for quality control, indicating the name of the artisan, the kiln, or the government office overseeing the work.
Market Trends
Growing interest in 'literati' objects and archaeological epigraphy among Asian art collectors.
Investment Potential
Low for generic construction marks; high if identified as a rare Imperial-grade commemorative stamp.
Similar Autographs
Ming Dynasty wall bricks, Han Dynasty roof tiles, or Yixing stoneware pottery marks.
Display & Preservation
Keep in a low-humidity environment to prevent salt crystallization; use a custom acrylic stand to support the weight.
Interesting Facts
