Pyrite is not very valuable for just the minerals. However, some people collect mineral specimens and might offer quite a bit for an excellent sample of pyrite. I just did a search and found some specimens selling for several dollars a gram (5 carats). So, if your rocks are very pretty and show lots of crystal detail they may have some value. Find a rock hound or gem and mineral dealer in your area and show him what you have. You should check on different websites thou.
