Do they only stay for the events?

What do you mean?

You get the when you shaman each time you get saves.

Like after the event ends are shaman coins still collectible or can you just get them when a event is going on?

You still can get them when the event ends and a new one comes.

Most of the currencies if not all stay in the game aslong as the shops in village remain.

what are they even for you cant trade them

Shaman coins are permanent. You can use them to buy a title, a cartouche, a badge, and consumables in Village rooms. The Transformice Wiki has a full list of what you can spend your coins on.

If you have any other questions in the future, please use the Questions and Answers thead.

Thanks!
