Hello, Would someone kindly explain to me how to identify a 1979-P SUSAN B ANTHONY COIN on a Quarter Planchet. Thank you. Tom
Is your question because you think you may have one? If so, post photos, it'll be easier for us to give you the most accurate diagnosis.
A Susan B will weigh 8.1g, and a Quarter will weigh 6.3g. The weight difference will be obvious. And as Cascade mentions, a Quarter planchet is so much smaller that it's unlikely there will be enough metal for a complete strike, and if there is the coin will be noticeably thinner.
Yes, they do, don't they? Silver ones weigh 6.3, though, which is what I looked at in my haste to get an answer posted.
