Having yard sale today: how much should I ask for Huffy Sea Trails 3 speed antique bicycle?

Question

Its in very good condition, just needs dusted off

Answer 1

It might be old... maybe even 25 or 30 years old.. but it certainly isn't an antique.

The bike is virtually obsolete and there are literally millions of them around. I would be happy to get $20, but would accept $15.

Answer 2

An antique has a year.  Just because you say it is an oldie, is it worth more than the going rate for a u.s. steel bike?
