I recall a claim 40 years ago for a counterfeit cashier's check on a Mercedes, about $30K.
IThe ones I've seen lately look a lot harder to fake.
Wire transfer is probably best if cash won't work.
For stuff like that & Ebay and other stuff I have a separate account with a small balance I can risk being hacked.

I think there must be a dozen threads in the archives on this situation, if that helps.
