I would never categorically say "yes!" or "No!"
For me it would be a case as to whether I like the people or not. Just like with anything else in life.
If I saw they were really very interested in their family history and were nice folks, I would say "screw it, here it cost me EURXXX and I spent EURXX on postage, research etc... so take it for EURXCV"
and I will use the money to buy me something just as nice.
If I thought they were arrogant SOBs and were not that interested, I would tell them to dig deep.
An old School friends mother just sold her paternal grandfathers WW2 medals last month and she is REALLY POd with her mother. The mother said "I never did like the old Bastid" and my old school chum is fuming because she was never asked if she wanted them. Mother sold them for EUR3 for each medal :rolleyes:
