Looking at the base of that eBay photo, my first thought was that it was rather brown as though there has been a leakage in the past. My guess was that they probably suspected that this was either a goner or might spark if plugged in due to any number of possible shorts, so therefore £50 for "untested" would be a better return than £5 ono for burnt offerings.
Having looked at the other photos on eBay, it looks more like sticker or glue residue, possibly from adjoining hardware. I think they tested and found it dead. Back in the day, when I went to computer fairs "untested" was a polite way of admitting "we can't fix this".
