Well, I just received my package of bhCoins V4. and I like them, but V3. was a better in my opinion. I really miss the certificate of authenticity that was included in that version. This version has a nice envelop, but what's inside is very plain. It's just a piece of paper with two QR codes, the addresses and the private keys.
EDIT: I just checked and the addresses on the piece of paper matches none of my four coins. Why?
