Worth buying or not?

A friend of mine wants to sell his collection but i dont know if it is worth to buy them all. But i wants to get rid of them all in one purchase. Most of them are german.

Here are the photos he send to me: imgur.com/a/ntzb6

What do you guys think?

Condition plays a big role as it looks like more than a couple are in poor shape. The Registeel alone could be worth $70-$100 but do you know the condition? I’d value the collection conservatively at maybe $180-$200. Of course more if the big hitters were all near mint or better :blush:
