An important thing to know about the appraisal process is that while appraisers are experts in the area of appraising, they do not authenticate works or collections. The team at Guernsey and Associates, Fine Art of Appraising, is well connected with area galleries, museum personnel, dealers, auction house owners as well as many appraisers in other specialties that we consult with on a regular basis when completing appraisals. Access to this collection of experts, as well as other related-field appraisers, allows the client to have appraisal needs fulfilled by one service. This is particularly useful to clients with IRS, dissolution and estate appraisal needs. 

Each new appraisal assignment is referred to the appropriate appraiser who is an expert in the particular area being appraised. The expert will research and prepare the report under their name. Depending upon the assignment, the appraisal may be completed by one appraiser or several experts as a team. For collections that have items in addition to paintings, prints and sculpture, we bring in outside appraisers with areas of specialties related to specific items.
