heirlooms, the time has come.

One of my daughters really likes the cast iron I've given her.  The time has come to pass down my grandma's Griswold griddle and I trust her to keep it in the family rather than sell it. As near as I've been able to determine it's age, it was produced in 1909. it's way too big for me to cook on, living alone, I typically use only about a third of it to cook on, it actually gets in my way. Many years ago I gave her a round 10" griddle (flat, no sides like a skillet) that came from a friends estate. I'm thinking it's a bit small for her family size and it would be perfect for me. Do you guys think it would be crass to ask her to trade it with me? No matter what, she will get her great grandma's griswold. I've already passed down my Dad's guns,(my nephew absolutely loves his grandpa's 1947 m12 20 gauge). This is the last heirloom I can think of to pass down.  I'd hate to think I'll die and these things will just go to auction. I tried to give my m96 to a friend who treasured it but he insisted on paying for it. He loves that old swede as much as I did.
Sorry to be so morbid, but recent events have me thinking about such things.
