Maybe a few cents because it is a wheat. What you have on the obverse is a die chip on the 5. Fairly common. I'm not seeing what you are trying to show on the reverse though.
It's all good This is a good site to check out. You can search your coin for what you think you have and see if there are any listings for that year/mm http://coppercoins.com/advsearch.php
Post your future questions on the Error Coins forum section on CoinTalk.. First find out if it's a true mint error or just damage.. then worry about what it is worth.
