I met a woman today whose family has had a 1920 Gibson A-9 since it was new. She has asked me if I could get her started down the path to assessing its value. I don't have a photo so am trusting her when she says that it's in very good condition with the original case. We're both in SW Florida and the A-9 is in Michigan. One suggestion could be to take it to Elderly Instruments in Lansing for appraisal when she gets home. I'll also do some checking on eBay for her. Any other ideas? The center of my mando world is Boone, NC , so I don't have contacts down here in Naples...any help is much appreciated.
