Nice nickels! Buffalo's are tough to grade because some years have stronger strikes than others and what looks like wear may just be strikes. I am no expert on Buffalo's but this is my swag at it: 1913 D type I - MS63 (is the stain on the reverse rim damage?) 1913 type II - MS62 1914 - MS62 (light scratch and rim ding) 1915 - MS62 1915 D - AU58 1925 - AU58 details (looks like a pretty good scratch) 1927 - MS 62 1927 S - AU50 1935 - MS 65 (die clash under chin?)
What I find interesting is that when looking at the pictures for the grades - the MS64 shows a weak strike, but I have seen the same type strike with nice luster graded a 65 or 66. Interesting the dates they picked for the grades - I don't know dates by heart, but read that some of the denver and san fran mint marks are notorious for weak strikes.
Buffs are extremely difficult to grade. On several, the difference between XF to AU or AU to MS...well, the dollar amount can be quite substantial. I have a fair idea of the grades. Posted without my input to ask for everybody else's opinion.
Your photos make grading the coin (judging luster) practically impossible for me. The last coin appears to be at least a 65. Nice coins.
