name 4 "corner stone" calls to start a collection around.

[Happy hooker]

I would add a Lonnie Mabry box call,,,the fact that he won't ship or mail calls make them future collectables right there.

Marlin watkins long boxes will be worth a lot in the future.

[KentuckyHeadhunter]

I would add Darren Dawkins to this list. 

[strutnrut]

I'd add Mark Sharp, Dan Harris, Matt Mclain, and Russel Beard. I'd also grab new a Lonzo pot call or two.
