Hi, welcome to Just Answer and thanks for your question!
This piano was made by Samick in South Korea and the serial number you provided dates it back to 1993. Samick produces a high number of glossy black baby grands under a number of different names for the North American market. They are lower priced instruments compared to other Asian brands and often are sold with player units, like yours. Since not all buyers want a player system with their piano and because technology is constantly improving, the player system itself depreciates faster than the piano. Based on your description of the condition and figuring depreciation in value with age, I would recommend a current selling range of approximately $3,600-$4,200. Best wishes!
