I don't think they're in business anymore so the address on the slab may not be accurate.
International graded coins in the mid to late 80’s. The back of every normal production slab has a copyright date of 1987 and their slab is nearly identical to the more recent Global service and even has the hands holding a globe that Global uses today.
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.
