PCGS and
NGC are the top tier. They house most of the top coins. Look at any decent to high end auction house and you will mostly see their slabs.
ANACS is in there too. They might not carry a value premium like PCGS/NGC, but their fees are much more affordable and are a really good option if slabbing your collection for in-house purposes like safety, variety attribution, or preparation to hand down as inheritance.
ICS gets a note because they have met the criteria for eBay.
You might see SEGS from time to time. Not sure if still in business though. But lots of folk like their labels and solid cases. Enough variability in their grading that some got burned with an over-grade and others cherrypicked gems of undergraded. Be the cherrypicker.
