Our gallery recommends appraising every collection. We offer appraisal services for European Art Pottery collections dating from 1880-1930. Appraisals cost $200 per hour, with a 10 piece collection averaging 3 hours. Our fee for a single object appraisal is a flat rate of $100. Need to know the value of something you want to sell? Updating your insurance records? Whatever your motivation, it is recommended that important collections be reappraised every 3-5 years.
