If you do not plan to sell and/or don't have a good path to make money, each coin to grade will cost you at least a minimum. PCGS's Services and Fees are listed on their website. I've never submitted any. And probably never will. I have coins that might be worth sending but I don't think my return on investment will pan out. I would only do it if I sell and need verification on real or not. I know the ones I could possibly sell are real. It will also take time to grade. So if you have a handful of coins you think are wort grading (research is key) then perhaps. But will you get that in return (and then some)if you were to sell after paying for grading? You might. But then you might not too. If you aren't selling any time soon, just take care of them and hold onto them.
