Thats going to very chapter by chapter and also influenced by what Plot emphasizes for ritual scrolls.
One chapter may have a cool Plot point with Mist Sense where it sells for 10g due to its importance and another chapter sells 1g
Best explanation I have heard on how pricing on ritual scrolls goes is that it's like the stock market. Prices jump up and down depending on where you invest and the demand in the area. There are some that will go high all the time (like Claire mentioned above) but even then, I know people who have bought them for incredibly cheap to turn around and make a huge profit because they found the right person. Some people in this game spend a lot of time watching the ritual scroll market. It's a wild beast.
*This is opinion based on my experience in Midwest chapters. Others might swap around some, but for the most part, I'd say these all are always going to get at least few bids going*
