+1 Misaligned Die Strike. Unfortunately, the strike on the coin is not "off" enough to be called off-center (both sides need to be off also). On the other hand, I think a comparatively recent year of 2006, plus a "D" may make it a little less common compared to other MADs. Most MAD dimes seem to be from the "P" mint. Just my thoughts.
An MAD is only on one side, cause one of the dies is misaligned (duh). If it is on both sides, the planchet is misaligned and you have an Off-Center strike.
The 10 thou OOR is PMD. If you look closely at the rim, you'll see a mark /step at 7:00 and one above the T in LIBERTY. The rim was probably squeezed after it left the mint, resulting in the slight out of round. Since you said it had reeding, it had to have been struck in a collar.
Normally a MAD will still have both dies within the collar and it is the collar that determines the diameter of the coin, so a MAD will not normally result in an out of round coin. An exception would be if the hammer die is so far off that it is hitting the collar and pressing it down out of place. I agree with Oldhoopster that the coin rim has been slightly flattened from 9:00 to 11:00 and that is causing the out of round condition. The full reeding also indicates it was struck within the collar and would have been completely round initially.
To see if it is normal or also misaligned. As a general rule you always show both sides of a coin. Why are you even asking this question? Do you really need to quote me?
If both sides are off, it's better than if only one side is off. Many coins will be off slightly on one side. If you look through enough coins you will see some. As far as errors and value go, the more drastic the error the better. So if it is only slightly off on one side, there's really no extra value. The more off it is the better.
