1. How do I buy 10 Bitcoins ?
2. Are they are real ? anyone tested them and could redeem for Gox Bitcoin ?
You can buy quantities less than 50 from resellers. Look on Mike's sales page for links to resellers on ebay,
bitmit.org, and other sites.
I have redeemed one 2012 1BTC coin through Mt. Gox, and it worked flawlessly.
