The ATM check frontend is much less picky than the teller check negotiation frontend. And the backend generally doesn't care too much either. To my recollection, I've only had one check ever refused by the ATM backend, and that was because the issuer hadn't signed it (on accident... I got the check back, took it to the issuer and they signed it on the spot, no harm done). I have had ATMs refuse a State of California Warrant (like a check, but not because it's drawn on the State's General fund), but a teller took it, no problem.
UGH this reminds me I have one of those fricking Warrants, for 19 cents, sitting on my desk. I finally found out that mobile deposit can't handle them because they have no account number whatsoever -- merely a routing number and a check number, so the 'check processing' system can't make any sense of them.
(I need to deposit it because I want to get my full name and address out of the unclaimed property register, for obvious privacy reasons)
