ebonitekid767 - Citori Special steel? You sure that's the model? Most Special Models are 12ga. There's a Special Skeet model, in 20 ga, but you have to know what grade it is, to get an idea of the correct price.
I think what you might have is a Citori Upland Special. Here is a brief description: 12, 16,(mfg. 1989 only), or 20 ga. (2 3/4 in. chambers), shortened checkered straight grip walnut stock (14 in. LOP) and Schnabel forearm, 24 in. barrels, blue finish, Invector (12 ga. disc. 1993) or Invector Plus choking, 6-6 3/4 lbs. Mfg. 1984 - 2000.
Most of this description matches what you said except for the length of the barrels. 80% to 95% is from $600 - $800. BUT my Kellys Blue book is the 29th Edition, from 2008. Prices have gone up from then. Best of luck.

When you allow a lie to go unchallenged, it becomes the truth.
A statement of fact: H&R Huntsman & Sidekick blued barrels are made of 4140 steel.
