Here's something I just noticed...

I've acquired 5 pieces of Calphalon One (stick) over the last couple of weeks from TJMaxx and Marshalls. Of the 5 pieces, three don't have a serial number at the bottom. One has a 5 digit serial number. One just has a "0" at the bottom where the serial number should be.

Is there any significance ? Are the non-serialized ones not good for warranty purposes (ie quality control rejects or seconds)??? Is the one with the "0" serial code worth more ?
