Question I have is ...Where is the public key
Good question, i was looking for the exact same thing.
Are these being sold individually or in a roll like the bitcoin penny?
there may be no Keys attached to the coin just a numbered hologram
The public key came on a piece of paper with it, with "#01" written on it.
It has .01 loaded on it
Edit:
You can see a piece in of paper under the holo, it's raised slightly
