When you start out i believe it is 50 but it more than doubles once you put all the skill points into ledgermain. It's one of the skills under that tree anyway.
It goes to 110 with the first passive. Each passive after that only ads 10 more, so not sure if they are worth it.
Note, you get 110 for Launder and 110 for Fencing. So, collect those provisioning ingredients and Launder those, and Fence the more valuable loot. Then you can get 220 points a day towards Legerdemain, if you have the first passive. Otherwise it is just 100 total.
Enjoy the game, life is what you really want to be worried about.
