Currency Drops
I have this currency in the game called Infinibucks and the symbol for it looks like this:

Why this name? Because it amuses me. Recently I added currency drops from the various monsters when they are killed. Other drops are possible if you capture the monster, but a certain amount of Infinibucks drop if you annihilate it. The amount is calculated based on the tier of the monster and it has a bit of randomness to it. I have three levels of these currency drops as of right now: the smallest one gives 1 to 2 Infinibucks when collected, the middle one gives 3 to 5 and the large one gives 6 to 10. Also I added a little piece of code to overwrite that if I want, for example to make some specific monster always drop a large amount of currency. I might add to it or change numbers around later, but here is how those pieces of currency looks like when dropped:

The Infinibucks act as physics objects when dropped in the game until you pick them up, meaning they can drop to the floor, role down inclines etc. I took inspiration for that from the game Noita, but in my case the currency doesn’t disappear after a few seconds. Normally a monster drops a fairly small amount of Infinibucks, as I don’t want to encourage always killing monsters instead of capturing them, but I also added a tiny chance to receive triple amount of Infinibucks, just for fun. The first is an example of a regular drop, and the second of a monster that drops a bit more, with that triple drop:
