How much can I get for piano word rolls?

I inherited about 159 vintage piano word rolls from approximately 1920 or earlier. Are these worth anything substantial? How would I go about finding their value? Is it anything worth pursuing? I’d hate to sell them at a garage sale to find out later they were worth hundreds. Thanks!

Some could be valuable, but most are not. A lot of what was on piano rolls has been transferred to MIDI for digital playback… some has not, some are really not worth the effort.

Here’s a good listing of places that deal in rolls, new, used, and recuts
