I've asked White Rabbit about "Dr. Mabuse" because I found the text "Dr. Mab" in the image (border, in the background of the flames).
could you please explain how did you find that?
Sure. I create a layer filled with red and set blending mode to "color".
It should work in photoshop and krita (used latest beta) (did not try in gimp because I am not comfortable with the ui).
Now the background of the flames should become some hardly readable text. She really has a scrawl.
You have to rotate/mirror to get something readable on some sides. Additionally you can use curve, level, hue, saturation filters to enhance readability.
Some subjective interpretation of the texts:
N 1984 Dr. Mab....WASABI (might also say Dr. Mar)
CSI 6 E18 At 16 Sec (I mentioned this before. Not sure about the last part)
BRA BRAG Sahara 197 AMERA (totally not sure)
Ace....
Also the ribbons of the key seem to contain a number. See the image:

Edit:
Some other thoughts:
The twitter profile picture of coin_artist could be a hint:
https://pbs.twimg.com/profile_images/915914534430363648/fxPVth9e_400x400.jpgThe image has the red glasses I found in the CSI episode. It has spades (leafs could be spades).
Edit2:
Please use extended ASCII (e.g.
https://en.wikipedia.org/wiki/Code_page_437) for your decryption tests. I have a feeling it might be useful and it doesn't hurt.
Edit 3:
You can find many symbols/numbers/texts but as others have mentioned already it is hard to say what is real/important or just a side effect of the painting style.
