Judging from your pics, they look pretty good. Box, seal, and divider are all consistent with the stamped box date. Minor variations in length and cap application are acceptable. Cigars should have a noticeable box press if it is indeed ten years old.
Pick up a cigar and feel its weight in the palm of your hand. Cuban Coronas are typically lighter than non-Cuban coronas. Smell the foot of the cigar, it should have a faint stinky/sweet quality to it. This smell is stronger in younger cigars.
Ask yourself this, why would anyone go through the trouble of counterfeiting a box of Punch Coronas? This is not an expensive, well-known cigar. Most counterfeiters go for the Cohibas, Montecristos and Romeo y Julietas, usually the bigger, more expensive sizes.
Would I say these are real? Without seeing them in person I can't be 100% positive but it looks likely. Only one way to find out - "trial by fire."
