Simmons 2.5-7x28 handgun scope

I'm helping a friend take care of her dad's estate. This appears to be a unmounted in the box scope. Made in Korea. I'm assuming it's 10-20 years old based on his health in his later years. I can't find any information about it. I'm just trying to determine if it was a $50 scope or $200 scope when it was new. So far this lady has donated about $1000 worth of firearms stuff to our juniors club auction so I feel I need to make an honest effort to find it's value before gets rid of it. 
 
If this is the scope you’re talking about on my groundhog popper.
