My opinion. ANACS>NGC>PCGS both in cost and sell prices. ANACS being the lowest, and PCGS being the highest. As far as the companies go, I think ANACS does a fair "by the book" grading. However, NCG is stricter, and PCGS even more so. PCGS commands the higer sales prices I think because buys speculate it was undergraded and will grade up if submitted to NGC or even PCGS a 2nd time. ANACS sells the lowest, I think buyers in general think if it's resubmitted to NGC or PCGS it will down grade, which is possible. You dont' mention what you want to have graded, but as you see, it's not cheap to do it, so you want to be darn sure it's going to be worth the costs involved to have it graded. Let's say you found a 1998 Lincoln cent WAM FS-901, it doesn't make much sense spending $120 to get it graded when it sells for like $5 in average circulated condition, however, if it's gem uncirculated, this might change your math as you're in for $0.01 and then your $120.00 in grading fees if it gets to MS67 but you might break even at MS66 or lose at a lower grade. You want to carefully decide what to do on a case by case basis, and figure out if it's worth the cost to get it graded or not, or just waste money, people do that too! hahahahha
I tried this once with a coin dealer in southern Wisc...........and the syster tried to swipe my coins. It took me many months to get them back, so beware! He never sent them in to be graded , after telling me all along that he was waiting for their return from PCGS. I was able to persuade his nice wife to cough them up one day when he was out of the shop. There were 8 nice coins, the best being an MS 65 '09-S Brown IHC that I had graded last year from PCGS. I still kick myself for allowing this clown to do this. Looking back, there were signs that this jerkoff had "con man" written all over him, but I stupidly ignored them. I have met a bunch of other dealers over the years, who have all been great.
