It seems like NGC is the cheapest mainly because they do not charge handling and shipping. I find this hard to believe but I couldn't find it anywhere on their web site. Their cost breaks down as follows: Membership: $39 Grading: 12.50 That's about it. Couldn't find any more charges unless they are hiding them which I suspect. PCGS Membership: $49 Grading: 14 Handle/ship 17.60 I used the most inexpensive route to get one modern coin slabbed. Am I correct that I got the costs right?
Oh, yeah. NGC does charge S&H. Look at their submission form and you'll see how to calculate the amount. I believe they have the form online at their site.
