This is cool, i was not aware of this coin. I have written a book about crypto coin collecting (check my signature  ), and while I think that collecting can become much more popular as time goes on, I can say that you will have no luck getting anything near 100 BTC for this.

FIRSTLY, People that believe that crypro-coin collecting will go mainstream will also believe that BTC will likely go up 10x or 100x, meaning they are effectively paying 2m-20m for this coin, which is surely ridiculous

SECONDLY, despite all my research, I've never seen this. There is no 'story' behind it, and thus no history to speak of. For all we know, 1,000 exist, OR it is a one-off coin that you created. If I could sell a 'newly discovered' coin for $200,000, you can bet I would be manufacturing a coin with '2013' or whatever on it.

My advice is that you hold this coin; if one or two others surface, there will be a story to tell, and more info. I'd also like to add it to the next version of my book.  It might be worth something (but not 200K) in 3-10 years. That said, if you are very lucky, I could see you getting 2 BTC from some very serious collector.
