jay woltMW brought up a great point
the flips would sooner or later be caught by the public.
If duplication exists it eventually will be noticed.
If arbitrary cert #'s are used - they will not work when
the buyer adds the card to his PSA or SGC registry set.
Not everyone uses the registry for his cards but enough do
to cause a problem. Then when the authorities investigate
it will take no time to see where the cards were initially
bought from especially since most transactions will be from
eBay and easily traced.
