Cashier's checks are frequently used in scams.
One of the few ways to help ensure that it's a legitimate check is to accompany the writer to his bank and be physically present when the teller hands the cashier's check back. If you're worried about any magician's tricks about being switched, have the teller place the check on the counter and they You pick it up not the person trying to pay with it.
Since you've indicated that it's a non-local credit union, I'd be very wary.
You could always insist on a 'wire transfer' instead. And by 'wire transfer', I mean bank or credit union directly to your account, not Money Transfer services (e.g., Western Union or MoneyGram) or automated clearing house (ACH) transfers.
