App£e. or Appl€. Ideally you could use the $ symbol but there's no s in Apple. Sure, you can just throw in whatever character you want, but !nevets doesn't make a lot of sense.

what you're shooting for here is a pun. You want something that looks like a regular character, so @pple is kind of cute, but there are two obvious problems. One, it kind of looks like a direct message to pple, which falls apart. &pple isn't bad, but & doesn't have the association with money, so you don't get the pun.

There are a bunch of currency symbols you can use, there's a list here [1]. Check it out ₩₦€v€t$, then all of your currency puns will be money.
