I would post on Banjohangout.org to sell quick.
It is a Gibson Mastertone Copy. The tone ring looks to be gold plated but unknown in composition but probably brass. Gold colored Gibson clamshell tail piece. The tuning posts/machine can give an indication of the quality usually violin style gear post indicate higher quality. They should be marked if not one can assume they are Asian. No pics of the back but it can be seem that it does have a resonator which can raise the value. It has a bound rosewood fretboard, geared 5th string tuner, and a bound rim. Gold engraved arm rest and gold hooks. This generally indicates a high end of the line. Not saying that this is a high end banjo but certainly high end of thismakers line. It looks to me it is a Asian made banjo. Probably worth 500-800 tops.
It looks nice and this is what Asian makers do, they put all these bells and whistles on the banjo that catch the eye but do nothing for the sound of the instrument. Wood composition and fit of the tonering and the rim. The neck wood does have an effect on the sound but it is hard to say what the wood is. Generally neck woods are Maple, Walnut, Mahogany each being less bright than the next.
I found it here
Sonata - Seen gold plated, dark-stained flamed maple, clear head, clamshell tailpiece and carved heel and back of peghead, similar to Korean Washburn B-17.. The inlay design on the peghead is almost identical to that on the Washburn B-17. This one was circa 1995.
It was made by Samick who makes instruments for many different companies.

Still holding to the 500-800 range. It looks decent to better than average for a beginner. It should sell on the hangout pretty fast. Include pics of the back and any flaws, hard case or chip board, none. . Ya'll think gun guys are crazy, banjo players are in a league of their own. Ship double box, stuff newspaper balled up under the headstock, slack the strings, Insure the hell out of it and send Fed-Ex. NOT UPS!! http://www.stellingbanjo.com/blog/packing-and-shipping-a-banjo/
