Ok. From my 20 stamps shipment i got

2 REDS (ONE even has my name initials!)
3 YELLOW
2 BLUE
6 GREEN
7 BLACK

From the 5 stamps batch I got
1 RED
2 Blacks
1 Green
1 Blue

First Day covers from post office arrived today

1 Green
4 Black.


So i am very lucky from 25 stamps received i have made 3 COMPLETE SETS !

   I am not selling..so please dont bother asking.

  As per Kryptowerks calculation..

Chance for exactly 3 red stamps in a sample of 25 is .00184 or 0.184%. Meaning it happens less in 1 out of 500 times.
Similar chances for 3 *or more* red stamps in a sample of 25: 0.195%

You got insanely lucky.
