Eskate, you have a treasure in your hands. Don't rely on what any one person will tell you, ask around, take your time, don't be hasty in wanting to sell the bike.
I assume you've been here: http://www.classicrendezvous.com/Fra...cles/Herse.htm
and followed the links therein, and also here: http://www.sheldonbrown.com/vrbn-g-n.html#herse
By the way, the Sheldon Brown link contains prices that may not reflect current market conditions.
Occasionally these bikes show up on ebay, search there for selling price under 'completed listings'.
Do your research. Perhaps you'll want to keep the bike rather than sell it? Depending on location you may find an established bike shop with knowledgeable folks who can pack the bike for you.
