Destroying objects that have historical value (which is distinct from collectible value). As an exaggerated example, you wouldn't chop up a Dead Sea Scroll into tiny fragments just because it's useless as bedtime reading. The fact that collectors would be willing to buy very tiny pieces of dead sea scroll (perhaps collectively netting more than the sale of a single intact scroll) doesn't make it okay.
