Help with value of minor collector's items

No problem! Glad you're here, happy to try and help.

The calendars will have some variability in value based on whether they were removed from the mailer (or shrinkwrap, which looks opened), marked on, bent corners, etc. but they are not rare. I did a quick poke at ebay to see what's out there right now, looking specifically for ones still with their boxes if possible.
