Value is subjective based on condition true, but equally region. What market you’re in, what marketplace you sell within; eBay, Craigslist, Shopsmith FB Sales Group etc.
The motor is more likely AC and would not have brushes unless altered by someone who converted it to a variable speed DC motor similar to a recycled Treadmill motor etc.
You may find a range of values in your area by reviewing offerings over a period of time in you area. Completeness and the presence of optional accessories and special purpose tools (SPT’s) like jugsaw, Bandsaw, jointer and their respective conditions will affect values.
It’s not what it’s worth as much as what buyers in the market and timeframe you are selling are willing to pay, including if you have the ability and are willing to deliver it within reasonable distances if any.
Kindest Regards and welcome to the family of owners.
