It appears to be machine doubling. FYI The mintmark, "D" should be attached to the date when you're describing the coin. Like this.......1990D. Just thought you'd like to know! Paddyman is more knowledgeable in errors. Doubled dies are a variety.
Looks like MD but the photos aren't the best. It's definitely NAV or no added value doubling. Just worth face value. Welcome to CT.
Welcome to CT @Janie Haley. While your photos aren't the best (mine seldom are) it appears to be MD, or machine doubling. Check Wexler's site for additional information. http://www.doubleddie.com/144801.html As for posting photos, here are my guidelines. You should always post in focus FULL IMAGE photos (after you upload your photo, two buttons appear: Thumbnail and Full Image, click Full Image and your photo appears full size on your post and is easily enlarged by clicking on it. While it isn’t always necessary, it is nice to show both the obverse and reverse, even if your question is just about one side. Members can often give more valuable information having both sides to evaluate. Crop out superfluous background so just the coin shows, and post photos with correct orientation so members don't have to turn their computer in some awkward fashion to view it properly. Add close ups of areas you have questions about and make your questions as definitive as possible so we know what you are asking for. And try to have the best lighting possible to show the most favorable photo of the coin. Hope this helps in the future. Good luck.
