Just bought a 2016 Figured Turquoise ES second hand and upon delivery noticed that the Gibson guarantee sticker was missing. Guitar came with correct case, COA with matching serial number on the back of the headstock and even the original carboard Gibson box with SN, Model # and original store destination. Does anyone think the lack of the guarantee sticker in the body would decrease it's authenticity or value? I am not looking to part with it anytime soon, but I do want to make sure that i didn't get burnt. I'm 99% sure this is a real ES as it feels and plays similar to my others, but in this day and age, fakes are getting all to real.
