heirloom-type words

[darkoshi]

Is there a word that indicates that something has been in the family, or in your own possession, for a long time? Sort of like "heirloom", but not necessary involving multiple generations nor even multiple people? For example, to distinguish a Christmas ornament you've had for ten or twenty years versus a brand new one, or one that you've only had a few years?

Perhaps a word for a quality an object obtains in increasing quantity with age and familiarity?
(and perhaps with or without fondness... there could be ornaments you've had a long time, which you've never been particularly fond of, or not as fond of as others.)

Sometimes there are objects I've had a long time, but don't remember having gotten, so they are low on familiarity - like when you find something in the back of a drawer you must have bought some time ago and completely forgotten about.

Keepsake? For something that hasn't yet risen to family treasure.

Yes, keepsake occurred to me after the post. And maybe memento. Although new things can be keepsakes & mementos too. "Family treasures" is a good expression; that may come closest to what I'm thinking of although it implies multiple people.

Related adjectives, but these also don't necessarily imply age: Cherished, treasured.
Related nouns: nostalgia, sentimentality.

I still keep thinking there must be a noun (possibly from another language) for a "quality an object obtains in increasing quantity with age and familiarity (and fondness)".
It's not an intrinsic quality of an object, but the perceived quality / feeling it invokes in someone.
Sort of like "value", but that word seems so vague.

Ah, now I may have it, although in two words: "Nostalgic value". Or "Sentimental value".
