How Much Is WWII Nazi Germany Suit Worth?

Hiya I was just wondering my Great Grandpa was in Austawich and a Pilot and My Great Grandpa's Brother Was a Infantry they said they will give me their suit when they Die They have the Eagle Caring the Nazi Sign also The TWO thunderbots a German Cross and a couple more but a can't remember he won't show them too me until he Dies. So he has a couple of good years left in him he's in great shape he can run like if he's still 30 there's nothing wrong with a 80 year old man Running in the park xD so i was just wondering how much are they worth not that i'm gonna sell them
