I have one of those and one of the 2011 Casascius Series 2s. Would like to sell both of them, ideally at once,
but I'm unsure of how to conduct the transaction with assurance that I won't get scammed some how. Feels like the best case would be to meet in person at the bank where I keep them in the safe deposit box and conduct the transaction there. Here's a pic:

There are handful of people here that could conduct escrow for you. Escrow, unaffiliated third party, would receive payment from the buyer and coins from you and then send them out to the opposite person. Document the transaction in a thread here so it's public, which ensures proof that the person you choose for escrow is involved in the transaction.
Make sure you choose someone that doesn't have any controversy or negative trust in their past.
Here's a list of well known and verified escrow providers on this forum:
https://bitcointalk.org/index.php?topic=276897.0Using escrow on this forum is a very tightly controlled business, it's practically regulated. The community won't let new members offer escrow services very easily (I know because I've tried and been denied and ridiculed for even thinking about it). While that may be bad for competition and fees it's good for maintaining security for the buyer and seller in the transaction.
