It is true (and Polarik will soon show) that the lettering and symbols are different. But that could be explained by the two comparisons being 5 years apart. The one on the left in your posting was made in 2002 and the factcheck one was made in 2007.
Please understand that I realize the factcheck certificate could have been forged. I was only pointing out (many times in many threads) that it was created with an embossing tool (stolen or forged) and rubber stamp (ditto). Those are not impossible to steal or forge. I "get it" completely and as a result Polarik (and hopefully a few others) realize that the embossing could not be photoshopped, and the factcheck certificate had to be completely created (forged or not) including the embossing before it was photographed.
