Pablo, If you haven't found these yet, I'd be willing to part with a rack of $5s -- see pics here: Casablanca $5s
What condition are you looking for? Most of my chips are used, but in good/very good condition (no rounded edges, some wearing of cross hatching on chip face), although they very from very good/excellent (cross hatching intact/sharp edges) all the way down to 1 rack that is in OK used condition - which might go better with a well used set (slight rounded edges, some color fading ). The close up pics in the link above are from a rack that is in the best condition.
