Any idea about a Gemini Boss

[Rosco86]

I know its not what people like to do, but this one is out of my field of knowledge. Visting family in Victoria at Xmas time and Nephew told me he has has a green Gemini Boss in the garage that he has had since a kid. Is looking to buy the engagement ring and even after many uncle talks about "you know you are going to hell" he still wants to proceed, Was going to sell the bike at a garage sale for around $50 bucks if someone wanted it. Its obviously worth more, but how much? Had a look and condition is good original, all parts original, was going until throttle cable broke, no dings and very little rust. Is in Cranboune, Vic. What a reasonable price for a mini bike enthusiast for this item.

I Had one as a 14year old,
most remarkable thing I can think of is that
If you let the  clutch out   while rolling backwards it will start  and accelerate off in reverse ,

It's worth more than $50 most didn't survive the '70's. There was an article in VMX awhile back. I reckon starting price would have to be around $350+    Ebay it.
