I always have a recent copy of BBOGV.
Depending on the grade, BBOGV says it's worth between $17,500 and $3,500.
You can get a direct, written appraisal from the BBOGV folks by reading the instructions on this page:

Given the relative value of the gun, you may find yourself in the best situation by consigning it to Rock Island Auctions. Here's a baby dragoon example:

Remember, everything depends on the condition of the gun and what somebody is ultimately willing to pay :)
I don't fear guns; I fear voters and politicians that fear guns.
