I am blown away to see my earliest coins going for that much. It's crazy. Had I ever known...
With very few exceptions I gave away most of my early coins to people at work, I was giving them out like candy, what iwth BTC being $2 and all. So, those lucky ducks, if they still have them, have a prize.
I suppose if people are taking collecting my coins seriously, I might as well point out that the series 1 coins were made and distributed in prefix order, with 11xxxxxx being the first, 12xxxxxxx being next, etc. The lower the number, the earlier the coin.
There are two specific coins I can think of that might garner peculiar interest for rarity, if any of my coins could be described that way.
I only kept one coin from the earliest batches. I kept one whose prefix was "13kpu33y". I funded it in 2011, but decided not to give away becuase when I looked at it, and the way the font looks, it appeared to me like the coin said "13k pussy". Since these were coins I was giving away to promote bitcoin, I subconsciously set it aside because I wanted to foster discussion of bitcoin, not middle school locker room jokes. Had I not funded, I probably would have just ripped it open and thrown it in my "rejects" pile. So, that said, that's the only genuine original untouched funded-in-2011 coin I managed to keep. Even though it would be sweet to see four figures for it, I doubt I'll sell it.
There were two prototype coins I made out of the pre-production coin samples before I got the Casascius holograms. The prototype coins had a generic hologram, had a greenish solidified lacquer layer covering that hologram (since I was experimenting with spray coatings I ultimately decided not to do). Inside the lacquer layer I embedded a second outer paper circle with 8 character prefix, split on two lines of four. Of those four prototype coins, I funded only one of them so I could give it away. I don't know who I gave it to, but I know who of several people who possibly might have it. I suppose that's the only one that can be proven to have existed at the time having timely funding on the block chain. The coin is fully functional. I have the other one, but I don't think I ever funded it. Matters little, cause I'm not about to sell it either.
I have had people contact me to find out when their coin was minted, as though to evaluate its value. Just look it up on the block chain. I always fund the address after creating the coin (it would be stupid to do otherwise in case the coin ends up being a reject for whatever reason) so it is easy to establish a coin was minted prior to the date the block chain shows it was funded.
