The website is Abauniverse coin site and they sell on ebay.
A quote from their website "GCS - Global Certification Service: Global has patented a truly attractive holder which gives you more than a just a grade! Yes, we do give you a grade, but the INFOSLAB also features a quality, state-of-the-art, digital color photograph and an informative paragraph describing each coin along with its grade. These descriptive paragraphs are written by Jeff Garrett, Tom Mulvaney and other numismatic professionals. And, most importantly, the INFOSLAB truly protects your coins in an attractive holder like no other in the industry! Our insert materials include inert materials which retard any discoloration of your coins".
I hope you, the visitor of this web page, found this website before you purchased a graded coin at ebay or any other online venue. If not, don't despair, because here you will find all the information you need to buy graded coins without getting ripped off. It's better to learn this information now than never.
Ebay is only one of many websites that contain coin auctions or coins for sale in holders with an assigned grade. It's also apparent that uninformed collectors assume that a coin in a holder is authentic and graded appropriately, but such is not always the case.
It doesn't take a degree or training to buy coin holders, create the labels of your choice and encase coins inside. Furthermore, if you know how much coins are worth in different grades than you would be able to grade any coin, a grade of your choice, for the most profit. However, it doesn't stop there as many decide that can pass-off cleaned coins as problem free, or fake coins as authentic. If that's not enough, some have chosen to fake holders from the most respected grading services like PCGS and NGC.
So, I hope each visitor takes heed to the information contained in these web pages and buys graded coins accordingly.
