I do believe that the amount varies based on who is at the table and what are the limits. I've seen several tables with $5000 stacks.

Actually I've seen a craps game where the box had a couple of stacks of $25,000 chips ($4 million per stack).

The player walked away from the table, escorted by security, with a rack of orange $25k chips (actually the rack may have only had 3 stacks full). The table was roped off for 2 days. When I asked why, I was told that whenever the player is in town the table would remain roped off until he decides to use it.
