I guess I phrased that poorly...I meant the numbers..it's not like the VIN number on an automobile...
Ah now I gotchya! I used to pay attention to the numbers.. now I'm a fully-fledged SACD zealot (TM LizardKing!) I'm just thankful to get my hands on these suckers, some of them don't hang around for long enough to even check the numbers! :yikes
