Your art may indeed by as good as that of a well-known or even famous artist who sells for lots of money, but many other factors must also compare favorably before your selling prices can approach those of that artist. Your personal opinion about how good your art is has little to do with that artist's prices or why collectors pay them. If it did, any artist could sell any work of art for any price at any time. And don't make the mistake of thinking that your art is so unique that nothing else compares to it. All art is unique.
Every artist is unique.
Uniquess, however, has never been and never will be the sole criteria for setting prices at any particular level. Not only are they cost-conscious, but they almost always compare work from artist to artist and gallery to gallery before they buy. The more comparing they do, the better they get at collecting, assessing quality, determining fairness in selling prices, and getting the best bangs for their bucks. This is what good collecting is all about and what you're up against when it comes to pricing your art. At the most fundamental level, you must be able to make a fact-based case for what your art is worth.
