Anything is collectable as long as you can find a collector. As someone who's been in the hobby fir awhile, I'm just giving you an honest opinion. Could I be absolutely wrong? Sure.
Best of luck to ya.
This isn't a hobby grade product or a collector's item as far as I know. Perhaps in 80 years it may be worth something to somebody, but for right now, it's not really worth anything. $10 sounds about right.
