How many iron you should get for every crypt?

after this message I think 20 is a good number?

I average 60-90 on average per crypt, I've gotten as few as 24, and I've got as much as 124 (or 134, according to my friend, there was a miscommunication about ten of it, heh).

While you do get a good amount from the muddy scrap piles in there, it seems the majority we find in chests (at least in some crypts).
