As Bob has pointed out, this was one of the early production of the 1908 military, so not only were the dies nice and sharp but the novelty of stamping these critters hour after hour and day after day hadn't worn off yet. I'd guess a bit more care in marking the first pieces was exercised than in the many later pieces to follow.
Good observation on the double T marking Bob. Did you also notice that the second little crown that is found on the C/Z stamp hasn't been applied to either C/T? I guess Inspector "Z" needed additional supervision.
