I listened to a presentation by «Jim Konoske» on 11/15/2012 in Rosemead, CA. I’ve attended presentations by him before. He spent an hour giving free appraisals of the objects brought before him. He is very knowledgeable about many items and will tell you if he would need to do more research on an item to make a more accurate assessment. I’ve never come away from one of his presentations without learning something.
