Sorry but Friedrich is right !! Would have been helpful to know what you have that you want an appraisal on and why you need it !! Most items less than $5K can be found on ebay and many things over that amount !! Only high end items are worth the cost of an appraisal,, and even if you did get one that does not say that your items would sell for the same price as another same or similar item !!
If you do not know how to find the sold/completed items on ebay,, come back here and I will tell you how to find them !!
