I have a 1953 $5 silver certificate blue priest & humphrey but it doesn't have an * on it at all and the serial reads as follows B30737413A SERIES 1953 on bottom right hand corner below humphrey signature is G46 it has blue seal and s/n are in blue ink and on the back in the right bottom corner is 2180 question is I can't find this bill online without a * and there is no letter after the series date... is this a rare bill or what?how much is it worth?no rips no tares and no corners missing no pinholes just little fold mark in middle and little discoloration on bottom looks like rust or something...
