Marvel fantastic four comic book?

i have a fantastic four comic book, its from 1993 and still in the plastic so its mint and i been looking online to find a web site to where i can see how much it's worth. i don't really know a lot about comic books and just want to know how much its worth. i dont know where to find what issue it is. on the front it it says (headline) "if you thought carnage, spawn of venom, was a threat to mankind, wait till you see what dreadface is planning to do!" it has a pic of the thing with a silver helmet on with and wildstreak and other people. it on the bottom "featuring the new pulse-pounding premiere of a brand new marvel superstar" it also says "avengers emble A30th. 30 years 1962-1993" at the bottom it says "ryan/candelario" i guess there the drawers. on the back it has a add for crunch n munch and it has a trading card with it for "wildstreak" that's all i can really describe. if you have a answer about it just ask but i really want to know info about it. i had it for many years and i just want to see how much its worth. thanks.
