I live in Europe  PCGS, and NGC both have set up Operations here and they are both abysmal failures from my point of view.    What do I mean:  well  for one company I have to send my coins to Switzerland. Switzerland may be geographically in Europe but it is not part of the European Union.  So immediately there is a problem of customs duty going into and out of Switzerland. Yes there are procedures in place to limit unnecessary payments, but they are complicated. Complicated procedures make for greater mistakes.  The other Company is in France   so I have to send my coins to a different country in Europe, one whose postal workers seem to have considerable antipathy with the country I live in.   I have had diabolical experiences with parcels sent from France with sometimes the senders having to visit the manager of their local post office to sort the issue out.  Would you send you coins through the mail to another country.     It gets worse:   both companies when they receive the coins bundle them up and send them to America.   Would you use either company if you coins were going to have to travel through at least two different countries to get graded and then  reverse the trip. I won't.    The whole set up in Europe tells me both PCGS and NGC have done  very little work to understand the European collector. I will not entrust my treasure to firms that don't take the time to understand my needs!!!!

Have you tried any other service and had better results?

LOL  Third party grading is very much a USA coin market artifact. It has some appeal to me, but there is nothing parallel in Europe.....Unless you look at Italy were the slabs are modified plastic slips. There is only PCGS and NGC in Europe. At the local coin show  Numismata Wien (Vienna) I used to be highly amused to read  on their respective websites how successful their stands had been received... my observations were the opposite  the PCGS and NGC stands were the least visited. This year I didn't even see them at the show.  Such a  service would go down well but it would have to be customized to the European market  with graders based in Europe

Ah, I see.

Anyone else?

yes, me, i think pcgs graded too many coins and that some like ngc better than pcgs. i like anacs because of the price, ngc because it is easy to sent as an ANA member, but if i am buying and not submitting i buy pcgs, because i like the holder and the attractiveness of the case, even if it is not very acuratly graded, and i do not pay high fees for submissions.

For Canadian coins, don't forget ICCS. They're generally a well-respected company and are considered to grade accurately. 

I don't send in coins to slab.but did so for a couple just to make sure that they were not conterfit. Was at the ANA show and did it at the show.

 I like the look of PCGS holders better but I only have one slab from each PCGS and NGC and no others slabs so I dont know which is better. Also, I have a question: I have a world coin from Canada from 1953 which is worth $45 in MS-64 and $1100 in MS-66. What is the cheapest way I could get it graded from either NGC or PCGS, maybe even ICG? I dont have much money and I really want to know the grade because the value varies so much in 3 grades. Thanks

Talk to a local coin dealer to see if they can send in with there submissions. Especially if you just have the one coin to get graded. NGC has an economy tier but I believe you have to send in at least 5 coins to use it.
