How did you come up with 200k? If there were 3000 people in the very beginning, this amount should be much less. But I do not remember exactly how many were dropped off after the audit
1500 is the most commonly quoted figure these days.
There is an official Fund for the Silver Coins, it's Number 7 in the Richlist and contains 211,885,446.63 XEM.
1500 is roundabout the Number of official Stakeholders, so:
211 885 446,63 : 1500 = 141 256,964 per Stake
