Image from The Lincoln Research Center. O.K., this (my coin) is not the reverse of 1989. That said it looks a little different from the 1988 reverse. The "FG" appears doubled. The "G" doesn't have a sharp angle downwards but it isn't exactly straight. It appears to have a serif on top of vertical portion of the "G" and something sticking out of the bottom. I hope the close up is good enough to see it well . It's weird, so I'm keeping it. Thanks: Lou
Lou, honestly…it’s not weird. No need to keep it. All that I see is a stain…no serif. It’s a normal ‘88 with staining and wear, along with plating issues as well… imo…Spark
