They belong there if you collect them.
If you don't collect Borlands then I guess they don't belong in your collection.

I don't collect tokens so tokens don't belong in my collection either.

Now to your second question of do they belong in a guide book.
My answer to that is its none of my business if I didn't write the guide.

If I were to publish a price guide and decide to include Borlands, Harley Davidson chips or even fantasy brothel chips, what right does anyone else have to decide what I should or should not out in my guide.

Seems to me that would be completely up to the authors and if people don't agree they should not buy the guide.

No disrespect meant whatsoever but I suggest that next time you write a guide book that if you don't feel these belong you should not include them.

Personally I feel that Borelands as a collectable should be included as many chip collectors do actually collect them.
But I am far from telling the authors of any guide what they should or should not put in it.
Just my humble opinion.
