Authenticity card info needed

  1. I recently bought a vintage chanel on eBay, the serial number begins with a 3xxxxxx.. The card has a light blue dot on the upper right hand corner with CC circled in white on the inside of the dot. Also the gold trip on the card gives off rainbow color in the light? Can this be fake or just a variation due to older style? I thought I read some where that authenticity cards cann't give off color. I ouwld post pics but I dont have my cam. :sad:
  2. Authenticity cards should never give off a rainbow hue, regardless of the year of the bag.
  3. You could post pics in the Authenticate This thread. I didn't think 3-series has holograms on the authenticity cards, tho' ... I thought that came later.
