Not all comics are the same. If you are new to collecting Star Wars memorabilia whether it may be action figures, posters or comics, even though the item may look the same there may be some distinct differences. This is the case for vintage Marvel Comics- even thought the Cover may look the same, there are differences. here are some examples of Marvel #1 form my collection.
Top left: the rare 35c in the top left,
Middle: The first edition square- 30c, the more common first edition.
Top right : the third release is the first reprint with a 30c square.
The bottom issues were released by Whitman in comic packs, the diamond reprint – baggie packs. These are worth less than the original square versions,
