to see what value a FSB would be? Then see if it sells on auction? It maybe not worth the effort. The
seem to have more interest. There were less of these. To me the Roseys' seem to be more common? (Creating less demand) thus the winners for these might be the grading companies. IMOHO
OK just remember to check PCGS
for prices on these:
Nothing less than MS-65 listed.
So unless it is MS-67 or higher, then it would be at a loss to have it graded.
