Batwing #19 is on fire after news broke that DC is planning on replacing Bruce Wayne as Batman sometime in the near future.
This has caused all kinds of heat on Batwing #19 on the secondary market. Why? Well the rumors are they're going to replace him with an African American. Most have ruled out Duke Thomas so the next logical candidate is Luke Fox as Mr. Terrific was not deemed worthy either from most fans.
So most are rushing the back issues and gobbling up the first appearance of Luke Fox.
If you do find these, sell as it's reported that Bendis supposedly pitched the idea to just create an entirely new character to take over. So all this could be fear of missing out and those hoping to cash in on the likely candidate if DC does decide to dig into their vault for a replacement.
