Supposedly all varieties are edible but I have found some to not be worth the trouble as they are smaller and, even when roasted, difficult to crack open.

We routinely roast the seeds from pumpkins, butternut, and the larger acorn seeds.

As for saving the seeds for planting the following year, since squash readily cross-pollinate with each other most of the saved seed doesn't breed true. If that is no concern, fine, but most prefer to insure true seed by hand pollinating.

The Cinderella type of pumpkins have really large seeds and are worth the effort. I had one customer that used every bit, except skin of her pumpkins. The stem of 'cindies' dried make good substitute bobbers for fishing.

I dried some butternut seeds but they are too small.
Sugar Pumpkins were ok.

Sugar (pie) pumpkins seeds are less than 1/2 the size of the Cinderella pumpkins.

Ok, so what I'm getting so far is that they indeed are all edible. So trying out some seed to snack on won't make us sick or anything like that.
However, a lot of seeds are just to small to bother with.

Thanks for all the answers so far :)

Question: Do you eat the pumpkin seed whole or do you shell them?

I've found that all squash and pumpkin seeds taste good (with the exception of a white pumpkin I bought which had seeds that were entirely shell and nothing inside). However, I also eat the shells so even the seeds from mini pumpkins (about a half-inch long) are worth roasting, in my opinion.
