I'm going to be the devils advocate here. Probably because I really like being heaped with abuse. Lol.
If you look down to the US you can see that CAC is obviously VERY popular. I think there are a few reasons for that.
I believe that one of them is that the main grading companies all have a degree of inconsistency to them that some people feel the need for some reassurance. I don't buy
US coins but I have to say I've never really seen a CAC approved coin that I disagreed with. (I'm sure there are some, but I don't think very many) I feel like they've done a good job in only stickering coins that are obviously better than average for the grade. They've also done a tremendous job of marketing!
One of the other things that is different now from even 20 or 30 years ago is a lot more coins get bought without having the coin in front of you. Online sales, whether through auctions,
ebay, IG, FB or just basic websites have surged. We all know that pictures can be deceiving online and problems can be minimized or even eliminated in carefully taken pictures. That CAC sticker tells an online buyer in the US that the pictures aren't deceiving and they are going to be happy with the coin, not upset at some unseen hairlines.
I am also going to assume there are more high end buyers out there who don't know the grades as well as most high end buyers did in the old days. Those buyers like
TPG's for the assist they get in giving them an idea of the grade and I'd imagine they really appreciate the CAC sticker telling them that the coin in that holder is above average and represents the stated grade quite well.
I think it's easy as an older, experienced coin buyer and seller to look down your nose at
TPG's and companies like CAC, but most people can't grade as well as you. A lot of them know just enough to be dangerous. It's easy to say that they should just learn, but if you live in a remote community like I do that has NO coin dealers or anything to help with that, how do you do that? You can do some online but a lot of that can be misleading or even wrong. I'm learning to grade as I go and I make lots of mistakes. I look back on old posts from years ago and and shudder at how stupid I was, but we all have to learn somehow. I don't have the ability to go to coin shows all year long like some of you have and do. I think it's fair to recognize that some people don't have a lot of opportunity to learn except slowly over time and let them appreciate the
TPG's and the CAC's or CNAS's of the world. It may not be for you, but I don't think it's fair to say that they are a waste of money for everyone just because that's true for you. For every experienced collector/grader out there like some of you there are hundreds or even thousands of modestly educated collectors out there with a lot less knowledge who appreciate the help. And obviously buyers in the US agree because they can easily show how valuable a CAC sticker can be on a coin that has one. They are worth way more than they cost on virtually any coin they are on.
So in Canada I have no idea how CNAS will do. I'm sure, much like CAC in the beginning, it will be a very slow process to get established. It will obviously take years, and maybe even decades. I think our market is much smaller than the US, so it's not possible for it to be as large as CAC is in the US, but I think it can be an assist to modestly educated Canadian buyers, particularly those who shop online.
I do know the guys who operate CNAS, although not well. I've met them at one coin show. They are young and very passionate about coin collecting and grading and I give them kudos for putting themselves out there and trying to get established in our market. I will also say that despite being less than half my age, they are much, much better at grading coins than I am. I've heard people denigrate them because they are young, but they have put way more into learning how to grade coins well than 99% of the collectors out there and they know what they are doing. They have an eye for premium raw coins that I could only dream of. If you want to form an educated opinion of what they do, get to know them.
By all means don't use their service if it's not for you, but I don't think it's fair to put down what they are doing when there are lots of collectors out there who could use the help.
