Rogues Memorabilia
Out in 2011, this hand-painted lead figurine was made by Eaglemoss.  They’re a UK company which released figurines along with a magazine about each character.  Their general DC line is over now, but they’re still making lines of chess figures which are basically identical to these ones.
Professor Zoom here is about 3.5 inches tall and comes with the lightning rod from Flash: Rebirth (the cover of his magazine also uses art from the series).  Eaglemoss figures are nice solid statuettes.

This book for very young readers was published in 2014.  It’s fully illustrated (by Steven E. Gordon, who designed the characters in the X-Men: Evolution animated series) and has very simplistic text explaining the basics of Barry Allen’s history.
Several Rogues (Captains Cold and Boomerang, Mirror Master, and Weather Wizard) appear as antagonists working with the Ultra-Humanite, and quickly get beaten up.

This is something I only recently learned about.  A 1976 DC stamp set made by Celebrity Stamps, which includes a handful of Rogues.  There were actually six sets (Flash, Supervillains, Batman, Captain Marvel, Wonder Woman, and Superman), and one big album for the stamps to go in.

These were simply collectibles, not actual stamps for mailing, but they’re very neat.  Some of the art is clearly taken directly from old comics and promotional art, and some might be original (or at least I don’t recognize it).  There was also a Marvel set.

I don’t own this (I’d like to), but it seems likely that anyone seeking to purchase it will have to spend a fair bit of money.

This 2013 book lists all the hero and villain pets in the DC Super-Pets universe.  Many appear in the Super-Pets series of books, but I don’t think all of them do — for instance, Captains Cold and Boomerang and their pets have entries in this encyclopedia, but as far as I know they haven’t yet appeared in any books.  Professor Zoom and his newts appear in their own book, however, as do Gorilla Grodd and his pet monkey.
The art is absolutely fun and adorable, and the creators clearly had fun inventing all these pets.  It’s very kid-friendly and overall quite cute, and still readily available for sale.
(You can see the entries for the Rogues and their pets here.)

From 1986, this villain-centric RPG book contains character bios and scenarios for the characters to play.  The premise is about Goldface gathering villains — including several Rogues, but not limited to them — to become the crime boss of Central City.  It also contains maps of Central City, and while they can’t really be considered canon, they’re an interesting bit of detail for fans.
It’s a rare piece of memorabilia with Golden Glider in it, which makes it particularly noteworthy.  And there’s some original art by Carmine Infantino (he did the cover and a little bit of interior artwork), which is also of note.

This casino-style slots game, titled The Flash: Velocity, can be played at various gambling sites online.  It’s not strictly memorabilia, but games fall under the umbrella of Rogue-related merchandise.

This children’s book with colour illustrations was published in 2003, and depicts the Justice League battling a scheme by Mirror Master, Captain Cold and Captain Boomerang.  
It also exists as a black and white activity book for colouring and games.

Made by DC Direct, this Zoom figure in the JLA Classified line came out in 2010.  The line supposedly featured characters who were the most-requested as action figures, though I don’t know how true that is.  Frankly I’m not a fan of it; the body is far too bulky for the character and his face is a bit weird.  But some of us are completists, alas.

This 2012 figure is part of Mattel’s DC Universe Signature Collection.  Though to scale with Mattel’s DC Classics line, it was not released on the mass-market — the company had decided the figures weren’t profitable enough to release in stores.  Instead, the Signature Collection figures were sold online in limited quantities, and there were no more available once they’d sold out.  Fortunately a lot of small shop owners/dealers bought them as well, so they’re sometimes available at comic shops and from toy dealers.  That’s the only way you’re going to find one of these if you haven’t gotten it already (I saw one for sale at a convention a few months ago, so they’re definitely still out there).

McCulloch here is sold in a box with some nice artwork, and is a great 6.5-inch figure.  He’s very poseable, and Mattel even re-tooled him slightly in response to fan input about his accuracy.  His two guns can fit in his hands or the holsters, and their removable muzzles allow you to customize the way they look.  If you can find him, I think he’s worth purchasing.

This officially-licenced Super Friends shirt was made by Trunk Ltd in about 2011.  It’s deliberately distressed (faded) to give it a vintage look.
