The expensive one is signed in the bottom right, and also has some kind of red block print in the middle bottom.
It says it is a woodblock print, so these are the "originals". But print pricing is very dependent on external factors. An artist may produce 100 prints when he starts, but then when he gets famous (or after his peak when he needs $$$), someone gets him to create another 5000 prints from those same blocks. Both sets may look identical, but if someone can identify something that proves yours is 1 of 100 rather than 1 of 5000, it is much more valuable.
Also, as a practical matter, Dali prints are very often faked, so buying it from a real gallery who can provide a provenance is for the best.
Given all that, the details given on the Amazon Art page for this print are completely insufficient for anyone who is going to spend that much on a print. I would not buy one at a tenth that price without seeing it in person.
