Jack kit & Battery cover (98 Esprit)

When I bought my 86 Esprit the previous owner gave me a bunch of spare parts. A few of those parts belonged to a 98 Esprit V8 - specifically, a battery cover and jack kit mounted to a piece of round plastic I assume fits in the spare wheel.
I'm looking to sell these Items but not sure what a fair price to ask would be. If someone needs these please contact me at [email protected] and make me an offer.
I'm located in Mesa, Arizona.
