The 2nd run was a numbered run of 100 knobs yes and you got a COA.
The 1st run some ppl do like better, some don't, but it's basically the same
Knob with some minute differences, but nothing huge.
The first knobs were not numbered and did not come with a COA.
Not really sure if it matters unless you just intend to display it.
I bought one to use and one to display.
So I thought it was a neat addition in that aspect for display purposes only.
Just my opinion, affects nothing to the knobs cool factor and the absolute best
Shift knob I've ever driven with and owned... Just my honest opinion.
