My grandchildren are playing with their dad’s Legos. We didn’t dispose of them when he moved out but instead put them in a cupboard in his room. The grandkids now use that room as their own. I’m sure there is some valuable pieces in there but the kids are having fun with them so they will continue to be just toys instead of collector items. This is one of the joys of living in the same spot for 40 years.
MY Wife went through what we have. Completing all the sets. Value is $4-6 thousand.
We have multiple, completed Star Wars sets, that our son made, from around 2005 - 2009.
Millenium Falcon, etc.
