The roulette wheel style of the chip has a ball on both sides of the chip which actually shows the start of the message
So here is the code :
Lucky 38 side starting from the number 10 going clockwise
..--- ...-- ..--- ----- --... --...
200 on the house side starting at 7 going clockwise
.---- .---- ..--- ..--- ---.. .----
Can someone decipher please?
Edit: Fixed Morse Code Thanks Leharic
Also it the date of when the bombs fell and the date when New Vegas starts. Thanks Tales
