Can I get some feedback/opinions on this coin that I'm about to send to PGCS (or NGC) for grading. It's a 1964-D silver Roosevelt Dime that has beautiful crescent-shaped rainbow toning, graduating from a soft blue in the center to green, yellow, orange and red at the rim.
Your photos aren't in focus, so it is difficult to see any surface imperfections that would subtract from what might be a gem uncirculated coin, or if it is Full Split Bands. IMO there isn't enough spectacular color to warrant a Plus (+) or Star (*) grade from PCGS or NGC. As an example, PCGS value for MS65 is $14; MS66 $20; MS67 $30, so unless you have a voucher from PCGS or NGC as a collector club member, your cost to get this coin graded would exceed what it would be worth.
True, many 20th century coins aren't worth the cost of grading. However, when you have a special coin that you want to preserve, it may be worth it (to you). You can't get a gold bean on a raw coin. It would be nice to see clearer pictures. My initial thought of the first photo was "AT"...but the other pics look more natural. The scuff marks and rim dings impact the grade.
The thing about toned Roosevelt dimes, especially from the 1960's on, is that they are very common to find toned like yours and collectors of that series want the highest graded toners possible. Your coin would have to grade MS67+ or more to realistically make a profit.
