Can anybody appraisal my engineer unusual trio? (Searing Plasma/Vivid Plasma/GBH)

[Bong Rips for Karl]

The items are Brainiac Headpiece (Vivid plasma), Mining Light (Searing plasma), and Strange Trencher's Topper (Green Black Hole).

I've had the combo for a few years now after I stopped trading, and can't even remember what I bought most of them for, since it was over the span of a year or more collecting all three. All the old backpacktf data is ancient, as well.

Their likelihood of being sold together, or their individual worth. Any info would be appreciated.
