Prof Young, jgcoastie and our inestimable pax capture my thoughts. No way would I get rid of a legacy gun (how I wish I had one). I'm hoping mine will become legacy guns for those who survive me.
As to selling guns, short of financing a kidney transplant, screw that!!
Buy low, sell never, is a line I cribbed from some dear soul here.
Personally, I've enjoyed a varied range of firearms with, as jgcoastie says, certain go-to guns for any necessary daily use.
