Serial number discourage fakes and also can root out fakes when, or, if, they happen to surface?
A serial number, say #00 or #1 can increase the value of the piece because it is the first of the series.
Many people think that serial numbers are not important or are just for fans. Do not listen to those persons, for they are full of crap.
You can preorder without a serial number in mind to my knowledge
