I am trying to learn how to do this. Can you please tell me what you think and then a little on why? Thanks in advance!

The pictures aren't that great, but hopefully they will show enough to tell.

Tough one, since the left side of the jaw displays more wear than the right side. The right side suggests 3 1/2, but the left side is clearly 4 1/2. I would go with 4 1/2.
 
4 1/2

Here's why I say it's 4 1/2:

The 3rd tooth has 2 cusps. That means the baby too has been replaced, so it is at least 2 1/2.

On the 4th tooth, the brown is as wide, or wider, than the white part of the tooth (on the tongue side cusps), so it is at least 3 1/2.

On the 5th tooth, the brown is as wide, or wider, than the white part of the tooth (on the tongue side cusps), so it is at least 4 1/2.

But, on the 6th tooth, the brown is not as wide, or wider than the white, so he/she is not 5 1/2. Which means he/she has enough wear to call it 4 1/2, but not 5 1/2.
 
Thanks guys! I guess that I am doing okay as that is what I had come to as well so I am not as far off as I thought. Alan, I really appreciate the in depth analysis. That is what I was looking for. I have some more saved that I will look at some time and may post on here for confirmation.

BTW....this is the deer that it came from.

He only weighed 135 lbs, but that is about average for a mature deer for the hills, hollows, and hardwoods environment that he came from. He had above average head gear for the area though.

Last year at the NWTF convention, I took a jaw bone up to several wildlife biologists, Terry Drury and others. Basicaly what I gathered was you cant accrately look at a jaw and age a deer. Maybe you can sometimes but deer primarily eat different foods in different areas even in the same state, they also eat different foods in the exact same location based on acorn crop and other things. The deer i killed was atlest six based on trail cam photo's, noone at the convention could age him past 5. Some said definately mature and some said 5+ but thats the best I got.. Apparently Biologists have some method of taking individual teeth and putting them under a microscope and getting a accurate age, but i dont know much about that...
