US Entry Passport Stamps

One of my goals is to collect as many official US entry stamps as possible in my passport, from land crossing and also airports.
I think my collection is the largest set of these stamps out there. If anyone has or sees a larger one, please let me know!
I also collect National Park Passport Stamps and I am a member of the National Park Travelers Club.
