Seems to me this board holds a lot of the significant collectors/dealers in the hobby, which also leads me to assume there's a huge sum of money tied up in the collective collections on the board.
Which leads to the question... What exactly is the plan for your collection?
Sell it off before you pass
Pass it on to a child/loved one (who will almost assuredly sell it anyway

)
Let it be sold at an estate sale to make for some really happy/lucky new collectors out there
Etc etc...
I'm only 28 so my plans could obviously change, but as it stands right now I have no intention of ever selling anything, hopefully by the time I go, I'll have someone in my life that will appreciate it as a treasure and as an investment, that will keep it.
