Swords are always a bit tricky to figure out. Especially ones purchased by a tourist in Morocco. It's one of those things where I don't think you can get a clear answer from someone online because it's much better to be able to hold the thing and feel how well it's made. I've seen a number of swords that look antique/genuine but after feeling the quality, it is clear that it was never really intended for battle. Personally, I have a couple concerns just from the photos (keep in mind that I have a sword collection but I am not an appraiser or anything so take my opinion with a grain of salt). First, it has no cross-guard to protect the hand. Now, the cross-guard could have broken off as it seems the grip is broken but that brings up the second concern. The tang (the part of the blade that goes into the grip) doesn't seem to run very deep into the grip. So the questions are: Is it authentic and, if so, was it made for battle or was it meant as decoration? Those should really be addressed by an expert in person. Off hand, I would guess (and again, I may be wrong) that it probably isn't as old as it appears and it may just be a repro to sell to tourists. Even if it were an antique, it's in pretty bad shape. I think the earlier estimate of $150 would be accurate given its condition and if it's authentic. If it turns out to be made to look old for tourists, maybe $50.
Again, I could be wrong so I would try to find someone to take it to in person to find out.
