Can you still buy the Retired Egg?

Excuse me, I couldn't help but notice that you mentioned the "Retired Egg" in your conversation. Now, I'm quite intrigued by this term, and I'm wondering if you could clarify something for me. Is it still possible to acquire this so-called "Retired Egg" at this point in time? Are there any specific channels or platforms where one might be able to find and purchase it? And if so, could you perhaps elaborate on what makes this "Retired Egg" so unique or valuable? I'd greatly appreciate any insight you could provide.
