You can look at both PCGS and NGC websites to see what coins are included in a particular registry set. The PCGS and NGC sets sometimes include the same coins and sometimes are different.
There are several different
Roosevelt dime sets. Some are business strikes only, some are poofs only, some include both and varieties as well, others don't. Your coins may (probably will) fit with more than one set.
You can see the cost of getting your coins graded by looking at either the PCGS or NGC submission forms. Unless you can negotiate a price to grade the complete set, you will pay the per coin price indicated on those forms. Variety attribution is an additional cost.
