Collecting dust collectors

As I look around at all the nick nacks I have collections I have collected over the past 40 years, it makes dusting scary. It makes me wish I would have spent all those years collecting old money instead. Then instead of collecting dust they would have been collecting value over the years. And dusting would be a lot easier too. I wander what my kids will do with all the little trinkets I will leave behind one day. I have offered them to take any collectibles they wanted now instead of waiting but they didn't want any of them. Trouble is I don't want any of them  either yet they will remain where they are collecting dust.
