Genuine front panel - whats it worth?

Ive got a genuine front panel with crossmember attached,  part number 155-805-591-B (made in Germany). It has the VW stickers and stamps on it and its still bubble wrapped in its VAG box.

1. Which models of mk1 does this part number fit?
2. Im going to sell it as I no longer own a mk1  Whats it worth?

Many thanks
Rich

Difficult one tbh mate, while not rare they are not common to see about.  On ebay id expect £150 upwards but no more than £225 ish?

I'd have paid £150 for it a week ago!
