You could have easily tell what was inside it by looking at the post date on the envelope. Anything shipped gets an official post date from the post office which means it was shipped "X day" of "X month" of "X year". Chances are it would say "July" or "August" on it. Going with that, you will see the Nintendo Power logo on the envelope. Putting two and two together, you get a "This is a July/August Nintendo Power" 4.
Also, I would love a nice cellophane sealed game. They display FANTASTIC if you do it right- so I don't know what you're talking about.
"Never Been Read"...well, then if that's the case I have a ton of books that have never been read before but look like total crap. Does that mean I can ask exorbitant amounts of money for them? No. Also, if you know anything about printing, then you will know that it did NOT leave the printing company in that condition. So no, it's not mint.
Also, grading a comic book vs. grading a magazine is EXACTLY THE SAME. They're rectangular books, printed on incredibly cheap ass paper (glossy, or matte depending on the cheapass budget) that are extremely easily damaged. A coin however is made of metal and a baseball card is made out of paper. Bad analogy. Oh and it just so happens to be that Ninteno Power #1 is just one of the best collectible gaming magazines. I'm sure if an Action Comics #1 was crumpled people would still be willing to pay top dollar for it.
Finally, show you an exact quality item? How about one that's better?

That one only shows signs of standard wear from the top to bottom about 1/4" in on the right side.
And again, like others are saying. Just because games sell for $x,xxx doesn't mean that this game magazine should. I have a nice watch, but that doesn't mean a magazine with that watch advertised in it is worth a comparable value.

Got any of these for sale? Sell them to me. I also buy other NES Publisher inserts, and even GB/GBC, and SNES inserts too.
