Check eBay, especially in the sold items. That would give you a place to start. Call Black Dog and ask them if they would do an appraisal, but start with eBay.
I would look them up on eBay and see what they have sold for. This price would be a better national view of the value.
Im sure you could takw them there and they could determine a fair price. Plus you couldn see the awesome wearhouse of goods they have.
