OOH finally you got it, i was starting to get skeptical but im glad you got it, it looks really nice but i thought it would be nr 001 not nr 019, What is the price of one of those if you wanted to sell it?
Probably the market price of 1BTC , Azure will have a public key visible on the back of the coin, enabling him to verify it current value on the block chain.
He can cash it any time he wants by importing private key, which is hidden on the coin somewhere.
I suppose it would increase in value because of its vanity , the future would only tell if it would be of better value.
Some collectors would pay over the market price for this coin.
