Thanks for the info Hottohman,
It is true that non English (whether Arabic or any other languages) would not affect the value of any American comic book.
I'm talking about the first print non English comic books that were printed back in 50's or 60's. Those books obviously would have very low grades.
But let's say someone submits a reprint for grading and since the language is different and in addition to the lack of database about those international books, the reprints may get labeled as first prints with high grades.
Believe it or not, nowadays, international books are being sold on international auctiuons. And that's why any certifiying company should look into it in depth and have a reliable method to differentiate between first prints from reprints.
