"I went through the effort of creating this little overview based on official information, awaiting the new Series 4 Pins:

High Grade/Blue Quality:
Genuine Hop Pin
Genuine Hello AK Pin
Genuine Guardian 4 Pin
Genuine Vertigo Pin

Remarkable/Purple Quality:
Genuine Ancient Pin
Genuine Popdog Pin
Genuine Riptide Pin

Exotic/Pink Quality:
Genuine Shattered Web Pin
Genuine Dust II 2 Pin

Extraordinary/Red Quality:
Genuine Anubis Pin
Genuine Boss Pin

The info is based on a CS2 data leak published by good old GabeFollower (https://www.twitter.com/gabefollower/status/1639390244251357186)

The Genuine Pins will most likely be released at the first CS2 major in Copenhagen, March 2024.

Disclaimer: The color of the blind bag as well as the Guardian 4 Pin is yet to be determined. I say the blind bag will either be red, black or green. The Guardian 4 maybe green, red or white."
