Fr-1533 1953A Series Five Dollar Legal Tender Note having a seven of a kind serial number with just sixes & twos. B66666626A. B-A Block. Hard to find serial number on a Legal Tender note. Third Party Graded P.C.G.S #62 Crisp Uncirculated with some staining on the note. Just one digit away from a solid serial number note, which would bring $10,000.00 + in today’s market. Again, not the most common serial number to be found on an L.T.  Even the grade matches the serial number?
