unopened Playboy Magazines exact date Question. 0

[Carthage1]

I have about 60 unopened Playboy magazines from 2003 to 2010. does anybody know how to tell what issues they are without opening them? 
They have the approximate year marked but any assistance in determining how to tell which monthly issue they are without opening would be appreciated.

409

Eight of the mags say FEB09 so that must be the annual renewal day, only the last three lines ever change 

I was given a have a collection of Playboy magazines from 2000 to 2010. About 1/3 are unopened was looking to sell on eBay. It appears that opening them does not enhance their limited value.
