Thomas Plarail Original Engines

Hi there, I am a collector of TOMY / TrackMaster Thomas & Friends content. I was wondering if anyone has any of the original Plarail engines from Thomas and Friends made from 1992-2002? I have seven characters still new and sealed, what would you say would be their value?
