I recently purchased a NGC MS 65 1983-P quarter. Looking at the back I noticed that it is the Spitting Eagle variety of this quarter. It was probably slabbed prior to them recognizing this variety since it is not stated on the label. Is it worth re-slabbing or just leave it alone? I am not sure how rare the spitting eagle variety is or what its value is. If someone has some information they can share please do.
