carbon dating founders devil dancer neck label?

i was just given 2 Devil Dancers, one is 2012 and says so on the date stamp, the neck label is the round founders logo that has the ibu's 112 on the side and the ABV listed as 12%. the ABV is not on the body label though.

the second bottle, has no date stamp, the cap has a red tinge to the logo and the neck label doesn't say founders or have ABV or IBU's it says Devil Dancer. on the body label under Triple IPA India Pale Ale is states 13%.

i am told by my friend who gave them to me that the second one is much older than the 12 but she did not remember how much older.

i uploaded a photo here.
