Default Need your help please! Won't take but a few seconds of your time

I just got my Nexus 5 from Google yesterday. There is one thing odd about it. Here is a picture of the back:

The IMEI sticker looks all worn around the edges. I feel I can safely assume that is not right. It should be a solid black sticker. Did your phones come with a partially worn IMEI sticker? Makes me feel this phone is not brand new but a referb.

Please let me know what your sticker looked like.
