As an unintended consequence, I believe the ANACS yellow slab (the one right before the jungle green ones) will eventually command a higher premium- not because they are the best or worst but rather because their slab colors correspond with and represent a timeframe.  And the yellow slab timeframe represents an earlier time, which IMHO would lead to a greater buyer confidence of not being a fake vs being slabbed nowadays or later due to the amount horseshit out there now and continuing.  ICG might have some potential in this regard as no Cas background vs Cas background on the blue header, which would also correspond with and represent a timeframe.  Not saying this guarantees past ones can't be fakes or things slabbed nowadays are all fakes, but folks like odds and probabilities that lean more toward not being fakes and will pay at least a slightly higher premium. Don't get me wrong, I am typically in favor of slabbing due to the protection and preservation offered.
