Grading businesses make money by charging fees for appraisals and certifications of rare and valuable items. These services are usually utilized by collectors, antique dealers, and investors. For example, a grading business might target antique dealers as an audience to provide detailed analysis and appraisal of their antiques. This may include inspecting the items for authenticity and assigning a grade or value to the item. This service would be ideal for antique dealers to make informed decisions about the items they choose to purchase or resell.
