And for the newer members it's great to revive such informative threads. There's much to learn from them.
Although others apparently have had good experiences with outside the top two, I stick with PCGS and NGC. Wonder if the original poster took the advice and did not clean the coin?
In the grand scheme, NGC and PCGS are similar regarding reputation. I care far more about the coin quality than what slab it is in. Definitely buy the coin and not the slab. I would say from my experience that NGC is a little more (not much more) consistent. I always shake my head when I hear someone mention that PCGS "by far" had more strict of objective grading standards that NGC. I will say that NGC and PCGS have the best reputation and ANACS is behind - although for circulated rare coins I think ANACS is fine.
I have never submitted a coin, but I have a few that I am considering. That said, should I trust mine to a service that actually gave a nail a grade as an error coin? ?? Mac
No reason why not. The fact they're willing to engage in crass money grabs for stupid actions does not really reflect on the quality of their service. There are only two reasons - interrelated - for submitting a coin: To verify authenticity, and improve resale value (a large plurality of buyers will want a coin commonly counterfeited in a slab to trust authenticity). By and large, glaring mistakes aside, each of the 4 "major" TPG's are pretty good with authenticity (factoring their natural conservative approach so you understand they'll err on the side of caution). The "PCGS Premium" still exists, so they're usually the way to go when resale is planned, but that's changing over the years as collectors (thanks to the Internet) become more sophisticated.
I would suggest PCGS, just because they are more recognized as a good grading company. You could even get a premium on the coins.
I have a 2014 Wedge Tailed Eagle graded PR70 by PCGS. They put 2015 on the label in error. I contacted them and they offered to correct it at no charge. The seller claims this label error makes it more valuable. What do you think?
Not really, MAYBE and its a big maybe a slight slight premium to the right buyer but the majority of people won't care.
All of the (reputable) TPGs make mistakes. Even 5 9s means 1 error per 100,000 - and when you do 30M items, that's 300 errors. They call them mechanical errors. And they will fix them free of charge. It's worth whatever premium you can convince some fool to pay. This fool will pay about $5.
It's worth extra money only to people who know nothing about the concept of "value." Where else can someone believe an administrative error adds value? That's ludicrous.
Yes, I don't think anyone has actually tried to argue that it wasn't struck by the dies. That isn't even the first one of those to ever happen, they have been around for a long time, it was just the first to get that kind of publicity.
