The appraisal will also be good to have if you ever experience an unfortunate situation ( fire, robbery, hurricane, etc.) your insurance will cover the value of the appraisal.also it lets you know really what it’s value is- if someone approaches you asking for you to make them a quilt you will have a good idea what you should charge and if you gift it ( weddings, special occasions) it’s nice to include a copy of the appraisal for their insurance and it helps family members know it’s valuable and not just dump it when you are gone
