Ozark,
I wanted to stay away from answering your question. I've seen original Spencers listed for sale over a wide range of prices from about $1,200.00 to over $7,000.00 depending on condition, history associated with it, and what the market will bear. If you visit some of the auction sites on the Internet, you could probably get a "feel" for what yours is worth. Do you want to sell it? Or do you just want to know its value? Sorry that's the best I can do...maybe one of the SSS members who owns an original will get involved with your question.
