Just a friendly note, there is no need to provide argumentative information here. You asked for help and help was offered. Posting the arguments of your friend won't benefit your request. It most likely will leave a sour taste in everyone's mouth and people will be less likely to offer up information. If the garments are heirlooms, personally I would keep them no matter the value. It is a family respect issue. If your uncle wants to keep them in the family, I say give them to him. Again, it is a family respect issue. Just my 2 bits, take it or leave it.
