2 1/2 or older,
meaning he's no younger than 2 1/2, but is possibly "older" (such as maybe 3 1/2).
Guessing the antler score can be thrown off by whether or not this is a very small or a very large bodied deer, something that's hard to determine just based on these pics.
Just guessing the score to be in the ball park of 100.
Also, you have pics here of at least 2 different bucks.
Notice one has brow tines, one doesn't.
