What Are The Benefits To Having A Coin Professionally Graded

For red copper coins, TPG holders should help conserve the redness.

If you aren't planning on trying out for a registry set , which obviously requires TPG grading, then I would say that the primary purpose is maximizing value on a sale. Even if you aren't going to sell, perhaps your heirs will. TPG grading probably protects them somewhat from being taken advantage of if they sell.

If you happen to sell on ebay (whether for fun, to get rid of things you are tired of or to make a dollar), TPG grading is quite important. For example, I bought a couple of seller-graded "uncirculated" cents on ebay a month or two ago for $6 each. I am sure all other bidders dismissed the seller-grading assessment. I got them back from ICCS last week in MS64 Red holders. I expect to have no trouble selling them for $100+ each. Without the grading, I would be back at $6.

The whole concept of T.P.G.'s was to take the bias out of transactions between buyer and seller. Naturally sellers always wanted the highest possible price for their coin and over graded their raw coins. On the other hand every buyer wants a great deal of a steal and believed the raw coin they were interested in was a lower grade than it actually was. Voila, along came the Third Party Grading companies.
The T.P.G.'s: best known for certifying Canadian decimal coinage are I.C.C.S., C.C.C.S. and P.C.G.S. & promised both buyers and sellers and unbiased opinion since they had no vested interest in the coin!
Therefore, the buyer benefited by buying the coin sight unseen or nowadays on the Internet where it is impossible to view the coin via a 10X loop prior to purchasing. The seller benefited because the coin being sold had more credibility therefore resulting in higher yields for the coin on E-bay or a brick/mortar coin shop.
I know the bottom line is "buy the coin and not the holder", however, a few unscrupulous sellers in the past who were ripping off unsuspecting buyers eventually created a demand for T.P.G.'s.

Thats my story and I'm sticking to it!

Imagine having two coins-- an MS69 and an MS70-- and trying to tell which is which. Particularly on the fly, at a coin shop or show and the light is not absolutely perfect. I for one doubt I could do it with any reasonable amount of accuracy.

Basically (ideally) a good TPG allows a non-contestible assignation of grade and with it the value of the coin. It tries to take what was a subjective individual process and turn it into an "absolute." Also any varieties like a repunched mintmark or doubling can be confirmed easily, something which even experienced collectors can have problems with because often the difference is microscopic and there's so many of them.

Basically I think the point is that you know what you have in front of you... it is not a "really nice looking coin" it is an MS-65 coin. It is not a "strange looking mint mark" it is a d/s, listing #xxxx.

And of course the other issues already mentioned: a confirmation of authenticity, protection, assignation of value, etc.

Thank you.
there are a few points here I had not considered, I'm glad I asked.
I guess the hard part would be knowing where to draw the line, in other words knowing what value of coin is worth getting graded.

$6 that's helpful, this gives me something a little more tangible to work with.
Thanks Danlos

...except they do have a vested interest in the coin. Not directly, but I've read here that dealers who bring in more work for TPGs (in bulk) get the better rates. I'm sure they get some grade-flation as well.

The hard part - for me - is not authenticating coins that I know, but trying to authenticate TPG holders that I do not really know.

Where is this $6 figure coming from?

More bang for your buck when you want to sell.
