I don't think we'll jump into a war here because I think we're a bit more civil here, but you are asking a loaded question.
Some breeders list a price because thats what they can get for their rabbits. Other place a price based on the worth of the rabbit. I routinely sell rabbits from anywhere between $225 - $35. My breeding stock is pedigreed show quality rabbits, but not every rabbit produced is necessarily show quality. I also take into account 4H or FFA, youth, adult, wants, needs and what the future may bring for me with that buyer. IMO there is no such thing as a all-encompassing price.
What you will find is that show people know that a pedigree is nothing more than a piece of paper and is worth very little. A pet person might think its cute and look at it when they get it, but thats it. Some pet people feel they are getting a better quality rabbit because there is a pedigree, but that is in no way true.
Show people will not buy a pedigreed rabbit sight unseen if that rabbit or at the least their parents are not shown. Quality can only be achieved in purebred rabbits by showing. There is simply no other verifier of quality, with perhaps one caveat. Meat and commercial rabbits are quality as producers, their own weight gain and the weight gain of their offspring. They could look ugly as heck but still be good producers, but even then, well shaped rabbits produce better weight gain and feed to meat ratios.
Holland Lops are so often sold as pets you can probably ask quite a bit. That's value based on the market around you, not the quality of your rabbits. If you can get more than what you are currently charging, that is the free enterprise system and you can take advantage of it, but not everyone will condone it or feel the same way.
