Yes. I have a couple of silver ones. Prettier but never latched on to by the media in the same way. As you say, this is what many people associate with Bitcoin rightly or wrongly. They were launched to increase its visibility. It certainly worked.
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.
