    X-B Experimental Fr. 1602 $1 1928B Silver Certificate PMG Superb Gem Unc 67 EPQ.
    This well centered beauiful X-B Experimental Silver displaying bright paper, bold ink, and broad margins is one of only two graded at this elite level by PMG. The other note at this level crossed our auction block in April, 2021, where it realized $3,960. The X-B block was part of a BEP experiment that tested the rag content in the paper. The blocks involved in the experiment were the X-B and Y-B blocks of the 1928A and B Series as these two series were being printed at the same time and Z-B was the control block for both series. The X-B block paper consisted of 50% linen and 50% cotton, the Y-B block paper of 75% linen and 25% cotton, and the Z-B block regular paper. The results of the experiment were inconclusive. The paper our notes are printed on today is composed of 75% cotton and 25% linen.
