Not regarding event coffers, but only store boxes, once you get a card up to 10 stars they stop dropping - but I have now found, having gotten every common card I have up to 10 stars, that suddenly they ALL began dropping again. I was hoping that this would force the boxes to give rare cards instead, but it didn't - it just began to allow ALL the common cards to drop in store boxes again.
