I have this 1979 no mint mark Susan b. Anthony dollar with what appears to be but a blob. Is this an error? If so.whats the value?
Could you describe what you are seeing in a little more detail? Because I don't know what you're talking about. Are you talking about the mintmark next to her shoulder? That is an S, meaning it was struck in San Francisco.
Yes, that is an S. The mintmark that year was quite blobby. They redesigned it, but it quickly became blobby again.
