Yes, that is a tall bike. Some say that hurts resale, and I would agree, because it limits your target audience. Maybe you get lucky and find a tall person looking for a quality vintage bicycle. That's the hope anyway.
As far as it being chrome, I guess you have witnessed the inherent issue of rusting. The clear coat is only so effective and when it eventually rusts, the clear coat needs to be removed in order to remove the rust. Going forward a good wax and regular maintenance of same should help, as will avoiding riding it and putting it away wet.
I love chrome. Funny that the only fully chrome bike I've owned was a Bianchi Pista track bike that I sold because it was just too tall. Small world.
But I find the chrome appealing and hopefully a potential buyer does as well. Having said all of that, I'd list it as $300.00 OBO and see what happens. I assume all of the mechanicals are in good working order, tires decent, etc.
