One idea is to get him The Wire: The Complete Series DVD box set if he doesn't already have it. Another idea is to get him a book about The Wire, such as "All the Pieces Matter: The Inside Story of The Wire" by Jonathan Abrams. You can also consider getting him some merchandise from the show, such as a t-shirt with a quote or character from the show, or a mug with the show's logo. To make it even more personal, you can create a "Wire-themed" date night, where you watch a few episodes together, cook food inspired by the show, and even create a signature cocktail.
Or you can get him a star map with the date of your anniversary.
