Z Rims

[Superbeauty]

Hello, I have a set of rims that I am trying to find out what they are from and what they are worth.  They have the logo Z in the center so I thought they are from a datsun Z vehicle.The person who owned the rims past away around 1987.  Prior to this he had a Z car and replaced these rims with other brand.  These have been in a box stored for many years.

They are from a 72+ 240z/260z or even 280z.

The steel wheels underneath may have TOPY followed by date and size information (it will be around the outer lip of the rim).

What are you hoping to get for them?
