Dear 100 Hour Board,
should I get a class ring? will it ever be worth it?
-My Name Here
If you want it, get it. In my opinion, it’s not worth it, but for some people it would be.
Dear My ~
I got one. I wore it for years. Then I stopped and put it in a box to keep it safe. I have no clue where that box is now, though I'm sure if I dug for it I would find it. But I'm also certain it wouldn't fit me.
[shrug] It's fun, but it likely won't be a long-term fun.

A friend of mine was wearing his class ring at work and had the following conversation with an assistant or a secretary or someone:
Her: I like your ring. Is it an antique?
Him: It's my class ring from high school, so...
Her: So, that's a yes?
The joke is that he is old.
I can't stand wearing jewelry; I don't even wear a wedding ring. At some level I just can't relate to the premise of your question: will it be worth it? Jewelry serves no discernible purpose, so I can't imagine wearing it and being in any situation where it's like, whew, good thing I wore this ring, it makes the $X I spent totally worth it. So no, I don't think a class ring is worth it.
I don't think I've ever noticed anyone wearing a class ring in public - as I understand it, they used to be a big deal culturally, but most people don't care much anymore. I never really wanted one. I've never regretted not getting one. That said, if it feels important to you, go for it!
