Largest pot seeds you've ever seen?

Wasn't sure where to post this?
Anyway, what are the largest pot seeds you have ever seen? I am still trying to understand the very large seeds in a bag of Mexican 45? years ago or so. They were pot seeds. Biggest I've seen. Pot wasn't very good.
I just looked in the book Hashish where on page 18 there are some large seeds like what I am talking about? Can anyone shed any light on this?

Hindu Kush in '79 . Second to those were an unknown strain I picked up around '00 or so , it was mid grade weed that had either been dried or stored incorrectly . Maybe a dozen seeds per oz . At one point in it's life it was pretty weed . Grew them out indoors and it was great smoke . There was a lot of it for sale so I figured it was either large scale outdoor or greenhouse weed . Wish I knew what strain it was .

Certain Thai or Laotian lines can be big some Afghani and Iranian lines can be big too also some Pakistani stuff as well but the biggest seeds you will proly see is in lines that are also selected for seeds to be used as food hence the big size pretty sure all those places I mentioned use it that way certain lines/regions
