ANOTHER POSSIBILITY WOULD BE A SMALL CALIBER LOW VELOCITY BULLET STRIKE. EXAMPLES ARE TO BE FOUND IN MORO KRIS SO IT IS ALSO POSSIBLE IT MIGHT HAVE OCCURED IN KERIS FROM OTHER PLACES. IF IT IS PURPOSFULLY FORGED IN THE BLADE THEN PERHAPS IT HELD A BIT OF GOLD AT SOME TIME IN THE PAST. ITS A NICE LOOKING KERIS WITH A XTRA ADDED MYSTERY.
CONGRADULATIONS!!
