When setting up your book or art to publish, you will see the default is set to $5. This is the average price of a digital comic book. You can choose to set any price for your Digital Collectible or off-chain Digital book.
When deciding how to price your book or art, you should consider these factors:
What network are you selling your work through? A Digital Collectible may be worth more than an off-chain Digital item. Minting on chains like Ethereum can be more expensive than Polygon, which should also go into consideration when choosing a price.
Is this an exclusive or special edition of your book or art? You may then want to consider asking a higher price and offering limited copies.
Is this book part of a series? Offering lower prices for the first few books in a series can help draw in readers.
How much in demand is your art or books? More in-demand creators can typically ask more for their work.
Doing some research and talking to others in the industry is the best way to gauge appropriate pricing for your work.
