Watch List notes:

Costa Rica, 1 real, 1847JB, inverted B, "Madonna and child" proclamation issue, NGC AU details / cleaned. KM-65. Rich rainbow toning (mostly purple) over muted luster, choice grade and strike with evidence of die-clashing, the "cleaned" delimiter a bit unsubstantiated (looks like AU 58 to us). This can be a confusing coin for the uninitiated because it also shows the date 1846 as the year of landmark constitutional reform (unlike the far more common issues of 1849-50 with the same central design). NGC #4700529-009.
