Vintage original Hot Wheels Turbofire metal collectors badge from 1968

Description

Vintage original Hot Wheels metal collectors badge / owners button for the Turbofire car dated 1968 in excellent condition -see photos.  Metal pin is still fully intact and rear of button is shiny and not corroded or rusty.
I am the original owner of this. I packed up my Hot Wheels when we moved in 1970 and did not get them out after that. No one messed with them since. Sold the car weeks ago but just found my stash of the metal buttons.
Shipping to include tracking, insurance and proper packing.
