Both my kids took begginning piano lessons with Mr. Berri. It was a great foundation for their later musical endevours.

Quite a bit actually. As an accredited USPAP compliant appraiser I have to include the following: Cover letter describing the appraisal, assumptions, limiting and contingent conditions, the objective of the appraisal, the markets explored as well as the way in which the appraisal was done and finally a certification of knowledge. That's the appraising part. The other part is the gemology part and depending on what the item is will require expertise in determining what it is.
