The value would be around $50 in my book if the picture tube is not a dud.
That's a cool TV, but too new to be super interesting to serious TV collectors.
With every tube TV that old, you will need to replace a number of parts (mainly, capacitors) before it's safe and reliable to play. That is not a job for a beginner, since high voltage is involved and TVs are complex.
Meanwhile, I would not turn it on, which might damage expensive parts.
Hiring someone to restore the electronics would cost more than it's worth, but if you want to investigate that, this page has some advice on finding a repairman:

If you want to sell it, this forum has a Classified section where you could place a FS (for sale) ad.
If you plan to sell it on craigslist or eBay, you should warn shoppers that every old tube TV needs electronic work before you can expect to use it.
