Answer: It would be easier if you had provided the names of your hollies, but since you didn't, you can almost guess; male hollies typically have male sounding names (Blue Boy, Stallion, Blue Prince, China Boy, Mondo, etc.) and females usually have female sounding names (Blue Girl, Blue Princess, etc.). If you still don't have a clue, examine the flowers on both your hollies. If they are exactly the same, you have two males or two females. The males will not produce berries but the females will, providing there is a male holly nearby. If the flowers are different, you have both a male and a female holly and the female should produce berries. Male flowers typically have longer stamens; female flowers have a slight swelling at the base (the ovary). Hope this information is helpful!
