IIRC this was a kinda "common" pin back then. It was generally available through different vendors (around 2015+). Further, there were some variations of the same pin.
this is another variation, for example:

(although not 100% sure if I remember correctly) I believe it was also available at the bitcoin.com store, in bundles of like 5/10 pins, at some point....
I believe that I got mine from the official openbazaar merchant (paired with the openbazaar pin)... however many years have passed since then....
