Checked his FB page, similar badges are from June 2014.

So, I guess it should be from that date or before it. adr147 can give you more knowledge.

My mate's one looks like the one on the right. Single splice of Cocobola if I remember correctly.

Guess it would be around 2014/2015 that Raymond introduced the system of Red Green and Black plates. This Red Plate badge looks the same as the OP's Black Plate badge.
The numbered Black Plate would be after that I guess.

New Red Green Black plates introduced in 2016. There's also a brand new black plate out in 2018. You can see it on the Exquisite Facebook page.
