I’m not a collector nor any type of expert. My sense is that it is valuable, but as far as a dollar figure, I dunno. Prices for bicycles are relative; it ultimately rests on a number of factors, not least of which is the market: i.e. what someone will pay. The other factors like desireability and/or rarity is not something I can comment on, I dunno. But your bike is clean as a whistle and so I think it is valuable. And like I already said, it was top of the line back in the day. I would definitely have an appraiser look at it.
