The 1948-D Roosevelt Dime has a significantly large mintage over 52 million coins being produced. Therefore, finding an example in most grades should be fairly easy. Even in uncirculated grades up to about MS66 it is easy and affordable to obtain. In MS67 condition it is much scarcer but with some searching, examples can be found or purchased inexpensively. In MS8 condition or higher they are very difficult to find and collectors can expect to pay a big premium for examples in this condition.
