What Is A CAC Sticker Really Worth?

Is this why the CAC stickers are shaped like an "eye"?

I still can't believe that there are some dealers out on the interenet who do not show their coins.

My San Diego Commemorative Half is graded in an older (1st Generation?) PCGS slab at MS63 and has the Gold CAC Sticker, which subsequently means that in CAC's opinion, it should grade (one or two points?) higher than what PCGS graded it at. I paid a little more than I probably should have but I wanted the "gold" sticker...I am kinda vain that way.



Here is an excerpt that I found on CAC;

"Certified coins with CAC stickers have commanded bonus premiums because of the generally accepted perception that they are superior to 'unstickered' coins in the same grade - - " and coins with gold stickers have been selling for significantly more, often several times as much as coins of the same type, date, and grade that lack a CAC sticker."
"The green CAC are bringing 5 to 15 percent more on average, and coins with gold stickers are selling for roughly 80% to 90% percent as much as those already certified in the next higher grade."
Travers, Scott A. (2010). The Coin Collector's Survival Manual (7th ed. ed.). New York, NY: House of Collectibles. pp. 432

Its been done before, it consistently finds CAC coins sell for more. Theres a link to one of them on the first page

That CAC sticker will make the slabbed coins it graces more marketable. Numismatics is all about eye appeal and that's what CAC was designed to do designate those slabbed coins that were at least middle third or top third for the given grade. As always though when buying grade the coin for yourself and make sure that YOU AGREE with the grade and the CAC sticker.
