Re: [WTS] Casascius 2011 S2 1 BTC Brass Coins - EU - CoinFIRM - 2.4 BTC
these are 1 BTC actual private keys are stored on them? How do you see the private keys? It comes with a certificate? How do we know the coin is not spent? You are reputable and make a guarantee?
The private key is located underneath the hologram which needs to be peeled to reveal.
It has tamper-proof safeguards to prevent someone from re-attaching after this.
You can check coin's addresses on many block explorers to check the balance... like blockchain.info
And yes both the seller and the maker of these coins are highly reputable in the world of physical cryptocoins.
Casascius coins were the first and in most collector's opinions, the best coins out there
