Opinions on NOS T3 Headlamp Value

As the title says, I'd like opinions on a set of 4 NOS T3's value, I acquired them in '85 I believe. They have been in relatively well climate-controlled storage. I need to dig them out, haven't set eyes on them in 25yrs., so no....I don't recall if they have the vertical bars within the triangle. They were never installed, I may have lit each up once to check them when I acquired them.
Thx in advance, & @slantsixdan , what about the epoxy...any preservative moves etc. to them, or an "is what it is"?
