Modern coins sometimes generate less excitement on the forum. Modern are my focus.
As others mentioned, one coin per chat and also the photos are taken in a manner that might obscure details or issues. For coins above MS64 the right, or "wrong" lighting can make MS65 look MS67.
From what I can see though-- your double date dimes appears to be MS66. Small issue around 7:00 and what might be something around 2:00 but coin otherwise looks great.important to caveat that the lighting can "hide" things. But if the only issues are those visible from photo, id be relatively confident with MS66.
The colourd dime is more rare in MS65 and very rare above MS65. While the Obverse looks perfect, this is a good example of where lighting matters. In the process of adding the colour the coloured coins usually get a lot of small scratches. So yours would be either the unicorn or the photo is hiding a lot of sins. The reverse though shows the scratches I typically see on a coloured coin. Suspect this coin is MS64. If the obverse is as clean as the photo, you might get MS65, but I'm skeptical.
The commemorative dime (non-colour) looks MS64 at best. These can be found in higher grade with MS66 not being uncommon.
Hoping this helps and happy to see some modern coins shared
