I suggest letting the services crack them out too, especially if you select PCGS conservation. NCS/NGC has done a good job for me in the past but I'm sure PCGS would do a good job too.
If memory serves, both PCGS and NCS/NGC will examine any holdered coin to see if conservation is a viable option before proceeding.
PCGS will guarantee the grade after conservation only on coins that are already in PCGS holders. If you send them an NGC holdered coin, they will remove it from the holder, conserve it, and then grade it as a RAW coin.
I don't believe NCS/NGC has any guarantee after conservation on any coin including coins already in NGC holders. But they also won't mess with one unless they think they can conserve it properly.
