Which is exatly why you won't see me posting any details online. Some fakes are VERY good, but "Very" isn't "Exact" and as long as they have flaws, they'll be detecable. There's also more scientific ways to prove it beyond cosmetics and the info they contain (bad codes etc.), chemical analysis of the ink and paper, spectrographs, etc. If it ever got ugly and went to court there are plenty of ways to rat out the fakes, it's just harder than it used to be that's all.
