Cashier's checks are the easiest to fake. Years ago, I had a race car for sale. Got some e-malls from a supposed buyer. He ask me how much i wanted for the car and if I could ship it for him. I told him I can not ship, must pick up.
A week later, I get a cashiers check in the mail made out for about $500 more than the cost of the car. He explained that I should cash the check, then get $500 in travelers checks and then send the checks to a PO box.
The whole thing look hoky to me, so i took the cashiers check to my bank and ask it was real. After about 15 minutes, the bank person came to me and said it's fake. The banker pointed out the errors on the check.
Reported this to the local police, they did nothing claiming that as I did not loose money, they couldn't do anything. So much for the police helping.
