Yeah sure let me pull out my spare roll of Casascius Holograms. You want the 2011 error ones? 
Yes please. While your at it, sell me your blank and peeled coins too! you know, for my collection..
....but dont try this.... http://casascius.wordpress.com/2013/12/10/possible-counterfeits-to-be-aware-of/
Just so its fully clear, i was making a joke that anyone who gets both the blanks and stickers could just sell them as funded coins fraudulently
and yes, im aware of those stickers..seemingly they have not popped up yet
You don't have to explain man I got the sarcasm! The original guy asking for the holograms could have honest intentions and maybe didn't realize how his request looks pretty scammy, but this is bitcoin and anyone who has been here longer than a day is instantly going to put their guard up. I'm going to go with honest mistake otherwise he's the dumbest scammer I've seen to date publicly asking for "extra" Casascius holograms.
So honest answer; no, I don't have any extra Casascius holograms. These are pre loaded and any unloaded extra holograms leaves a wide open opportunity for a person to take an empty coin with an empty hologram and sell it as loaded and scam people out of a lot of money.
