Hey,

It could be a clip pedal like this one,

Notice that it should not make any difference to your idea. You should change the pedal with another regular kind. That is because the clip for this particular pedal is unique to this pedal and you may not have access to it.

As for it being worth anything ... you could exchange it to some plastic pedals on a mama-chari. I ain't giving you my mikashima.
