@canuck1us: Sorry to hear your set was damaged, at least it is only damage to the case and not the coins. I would have though that that type of case damage is easy to see and would have been pulled off the line during production/assembly.
When I got my set, I thought the medal was damaged/scratched. It turned out it was a deep scratch on the case. The
RCM may need to have a look at how its plastic cases are being handled.
I hope you can get a replacement! (If you want one!)
