There's a couple of notes I know of that are not in this list.
There is yoggs (1 of 1 AFAIK) custom serial test 0.2 BTC.
Also there are the red 20mbtc colour test notes, total mintage of 3 I think.
There is also one custom made Coin.Community note.
There's also a few test notes that I've seen on their instagram, but I'm not sure if any of these have been released into the wild.
