Hello everyone I collect first editions and limited exclusive collectibles.

Recently I've been dealing with a lot of J. K. Rowling books and collectibles.

There are several first editions that have been brought to me but I hear that J. K. Rowling doesn't sign many books except for charities and that she has used Holograms with her signature since 2007. However I always see two different holograms so my questions is which is real or are both holograms real?

Photos below

The first has J K Rowling stamped onto the hologram

The second has a date stamped onto the hologram

Thanks to everyone in advance for any help you can give me.
