Not much you can do with it now. They're just regular medals and you won't be able to pull any raid cards when the next even starts, or at least I've never heard of anyone pulling one from those.

I just wait till the next event, crack them open and use them to upgrade my cards. Or if I'm really bored, I'll do it in between events so I don't use up my Transmetal and to pretty much kill time in between events. But keep in mind they're not as powerful to use to upgrade cards in between events either.
