There are some older editions, including original German ones, for $400 and even more. But, Amazon often connects to unscrupulous booksellers who seek to gouge the unwary. I generally start with American Book Exchange when I'm shopping for used books. If I run into something of interest at Amazon, I'll still look at ABE, where, in my experience, there are more copies, better information about each, usually lower prices, and more reputable dealers.
As far as I am aware, the original German edition was a book club edition printed in 1931 in large numbers. It is still quite common, not a collector's item or anything near it. I picked up my copy for two or three Euro on ebay. Mind you, I did see one go on ebay for ¤37,50!
It is, by the way, one of the best chess books every written, so pick up a copy if you see one at a reasonable price -- just don't pay $400! ;-)
I would second the recommendation of ABE over Amazon. Even though Amazon do in fact own ABE, it seems to attract a better class of seller.
