1984 error over 8 in 1984 and a "blob" SUSAN B ANTHONY

HI GUYS, I wondered if anyone could tell me if a error (0 over the 8 in 1984) is valuable and if anyone can tell me if this is a d/p error of a blob on the SBA? I AM NEW at this and very thankful)) best D View attachment 987486 View attachment 987486 View attachment 987486 View attachment 987486 View attachment 987486
