So, perhaps I am out of the loop, but why would you bite a coin? Biting a coin seems kind of pointless (and potentially painful) to me.

lol thats the one i had in mind, biting into the gold coins. I tried that too, but not with a gold coin, didnt even know they are still around. Should try it with bitcoin 
Im not sure biting a digital coin would be a good ideaZzzzt ***gets zapped by electricity***
