Wow what a ridiculous mark up. Someone who has the time and money could likely successfully counterfeit that bar if they so wanted.
Good luck with the sale.
Well that would make them a dick. They can do all that, but they can't sign the address. Making it "unsuccessful".

I presume you mean that since they would have a different address they would not be able to prove the bar is authentic via the address?
You are right that if someone wanted to verify the address the bar has under the hologram to mike's public address list then yes it would be near impossible to 100% counterfeit it.
