You can try calling GameStop and saying your copy didn't come with a coin code (even if you didn't buy it from them, just say you did) and they will probably give you a code without asking you for any of your info..it's worth a try.

Or..... Change all the difficulty settings to 0 for the CPU, take Off-Side penalties off, make the games short, blitz every play and move your CB/LB next to the computers QB before the snap (it will even work on 4th down when they are punting). Your goal is to get four or more touchdowns, do this a few times and you should start seeing a lot of coins coming your way.
