Need advice on trading my entire vintage card collection

[darkhorse9]

Seeking thoughts from the realm here.

My card collection consists of complete sets. I have every Topps base set 1951-2019 (save for 52 high numbers), Bowman sets 1948-1955, plus other sets (Fleer, Post etc)

My plan has always been to leave these sets for my son when I die, but I have several concerns, not the least of which the difficulty that a non collector would have in selling the sets for the best dollar. A dealer would likely give just 60% of what a savvy person could sell them for on their own. Since my son is not a collector, selling to a dealer would be his best path.

Lately I've considered an alternative. I've thought about trading the sets I have now for a few key graded cards. Something like a PSA graded 1952 Topps Mantle, a PSA graded 1933 Goudey Ruth maybe a Gehrig or a Cobb somewhere and whatever else I can get for the collection. Basically I'd be turning my 100 set collection into about a dozen key cards.

Doing this would certainly make them lot easier to sell for my son. I can get a lot better deal for my collection now doing that as well. When he sells them he can get a lot better deal by selling them to collectors rather than dealers.

Would any of you consider trading away your lifetime collection for such an arrangement? As much as it would pain me to see my collection leave my hands while I'm still around it seems to be a prudent idea.
