That would be awesome,so in hindsight you are sitting on top of a gold mine and if so why dont you go for auction,i think you will grab a very good price too,there is no way the owner would have forecasted these sort of price being fetched for his coins and design. 
I plan to keep it for all eternity. And it's not a big denomination coin. I've kept the Casascius business card and mailing label for posterity anyway. At the very least it's one of the very last he sent out.
It's possible they'll become more and more valuable or fade away in the general consciousness. I'm curious to see which it'll be.
