C pillar stainless moulds

Hi to all,
I have an excellent pair of the stainless trim moulds that fit around the bottom of the C pillar where the vinyl on the sunbirds meets the paint.
Would anyone know what they would be worth to sell? As I have a guy interested in buying them.
As far as I know you can not buy them new and I can’t seem to find any others anywhere!
Any suggestions would be appreciated.
