I sold one a few years ago for $700.00 USD. It included all manuals for the calculator and two installed ROMS. The ROMS were Math and I/O. They may have changed slightly in value since then. The real valuable ones are the 9100A/B. Even though it's rare, most collectors don't really want the 9810 since it's not historically significant.
