It is good to hear that you are holding some coins but is it safe to say that those private keys are secure,i can understand the sentimental value of these coins but selling one bitcoin Casacius bitcoin for $7100 is just crazy because if i remember correctly it was revealed during defcon that it is susceptible to physical attack as they showed how to reveal the keys without revealing any tampering signs,i am not sure whether they made any changes after that,just commenting because of the crazy rate it got sold. 
Got them a long time ago, and one direct from Casascius one week before he shut himself down.
What is a more relevant question is how durable the holograms, printing and glue holding the hologram down is. I wonder whether he foresaw whether they would become so valuable.
