But its not just the age of this card which makes it hard to come by, this variant has several other factors that it very rare which Ill detail below: It is the Blue Back version, which is far rarer than the Green Back version which was printed later It also doesnt have the number, which was later included on the top-left of the card PSA doesnt distinguish between the No Number and Numbered variants in their population report, but of the 24 PSA 10s that exist only 2 are known to be No Numbered copies you dont get much rarer than that
Everything else is a welcome extra
