I know back in the pioneer days OO seeds were literally worth more than their weight in gold. OO was sought after by farmers since it grew quickly and could make a thick hedge (windbreak or "fence") in a relatively short time.
A bag a seeds (they're small and inside the fruit) was worth more than a corresponding bag of gold dust.
And when we were kids, we used to have fights with 'em too. Called them "monkey b@ll$".
