If you have a casascius coin which is still intact and is in good condition, I would advice you to better auction it off in the
Collectibles section instead of wasting your money in redeeming it. An unredeemed 2011 Series 1 casascius 1 BTC coin goes for around 1.3-1.5 BTC in auction whereas when you try to redeem the coin you would be receiving only 1 BTC.
The better idea is to never redeem a casascius coin and to auction them off. Hire
minerjones as escrow and post a picture of your coin with your forum name and time,date written in the piece of paper. It would surely fetch better returns rather than peeling the coin and taking out BTC.
