Actually, our design is the original IGR
These blue bars are editions before 2014 and probably other people/companies (incl. Apmex) are selling circulated gold/old stocks. IGR stopped producing blue cards in October, 2014.
As you can see from the official Istanbul Gold Refinery website (http://www.iar.com.tr), the color theme and assay card designs has completely changed and we have selling beige/gray assay card designs, which are 2015 editions. We directly sell brand new editions of gold and silver from the mint with a limited amount of stock and we are the only company that sell the latest original 2015 editions.

We had been selling Nadir Metal, as well but they are nowadays in transition stage for their new design and we stopped featuring them for a short time.
