Last year to my surprise, my E trade account actually sold shares I had on long term sell bid, but the value would appear or disappear from time to time on the remaining shares.
If you call a Broker at Ameritrade they may let you trade it.
I have Scottrade and I can't trade it online either because it does not have a Bid or an Ask and is on the Grey Market. I am sure if I called a broker they could try to sell it. No one is buying though.
