I'm assuming this hasn't come up already - if it has, please accept my apology for the duplication.
I just watched an episode of "Shark Tank", in which a pitch was made by a family who came up with a gel bracelet with collectable and tradeable coins in it. The coins have serial numbers on the back, and the owner can track the coin on its travels via a website, viewing comments by by the successive owners. Sounds familiar, doesn't it?
The really interesting thing was that the deal for investment in this business was contingent on the family's company securing the patent they intended to pursue on the process of having an online-trackable trading item.
If successful, what does this do to trackable geocoins?
