Token use by date

Unknown

This question has more than likly been answered before but cant seem to find it on the forum: im pretty sure the standard tokens dont have use by dates as there are some of you guys out there with literally hundreds, but what about tokens that u pull out of pvp? Once the event is over do u have a set amount of time to use it before it turns to a heroic/standard/completely disapears into the nether?
thanks.

IIRC they turn into heroic tokens if left for too long.

No, as of one of the recent patches, event tokens don't revert to Heroic tokens anymore.
