Here's a list of non-wheat error cents which I compiled from various sources. I doubt that it is comprehensive as there are new error coins being found regularly. DDO means "doubled die obverse", DDR means "doubled die reverse", MM means "mintmark", SD means "small date", and LD means "large date". The attributes listed after the colon are where to look for the error (for example, "1959 DDO: date; Liberty" means that there is a 1959 error cent with a double die obverse which is most visible in the date and the word "Liberty").
