If its a real Hawken, and most are not, then its almost priceless. The vast majority of the real authentic Hawkens are in museums or private owners who can trace their history back 150+ years.
100-300 USD
Sure. I like pictures of Hawken rifles.
Requires professional appraisal
Read books, look at real ones in museums, gun shows, gun shops and ask Hawken collectors.
Go to the website of the MAKER of your rifle (Hawken is a style, not a brand). You should find an owner's manual you can download, or request a paper copy for free.
You need a professional appraisal. Fakes abound and are vey hard to spot if you are not familiar with the item in question.
One of the better sources is the blue book of modern black powder values.www.bluebppk.com or from www.midwayusa.com

what is this rifle worth?
Sears Roebuck did not make quality guns, they made affordable guns so its condition is everything! 100.00 - 150.00 tops! Best luck!
Impossible to answer without knowing who made it.
