TWO HOLE IN ONES IN THE SAME MONTH

TWO HOLE IN ONES IN THE SAME MONTH

What are the chances of getting two hole in ones in the same month from the same sleeve of Pro V1 golf balls. Well I did it on 6-3-14 (Pebble Creek in Taylors, SC) and 6-29-14 (Willow Creek in Greer, SC). I dated each ball and saved them. I still have the third ball from that sleeve and don't know if I should save it or play with it? Any suggestions on how to display the two balls or even the entire sleeve?
