What years does it cover...
The Keith-Barry-Grondine flame wars are collectors items, and fetch a premium.
While the TB 'butt-monkey/moon-bat' years are not highly valued, and generally considered to not be the Zone's best work.
The 'flying black triangles' and chem-trail episodes are largely ignored by serious collectors.
I would take your collection to a certified Forum Database Appraiser (FDA) for an accurate valuation, and get it insured appropriately.
