Came across a batch of stolen MLB Authentication Holograms while doing some research. They are LH968384 thru LH968500

and the database says on each.

Hologram number LH968500 was located in the MLB Authentication Database under DESTROYED HOLOGRAM.
Session Product Description: STOLEN HOLOGRAM, PLEASE CONTACT MLB SECURITY 212-931-7800
Session Name: DESTROYED HOLOGRAMS
Session Date: April 27, 2010
Autographer:
Authenticator: AUTHENTICATORS, INC


If you know of other series of holograms that are invalid or stolen, please add to the list.

Another reason why you need to check the online MLB Authentication database even if there is a hologram affixed to the item you are considering to purchase.
