Great Grandpa Macero 1856-1902 marked this as 1840P date unknown. passed to his son,then my Dad + then me about 1960???. I had to go out and buy a 1840-O to a long time ago fill in the my seated dime set + no I do not Own 1873-CC!!! 12/06/2012 my son gave me a new Dansco album for my birthday. 12/10/12 my son found the Very Faint O and that when the story begins. New Orleans mint struck this thru something it showed up on OBV +Rev but the reverse strike made the O very hard to see. as "Paul Harvey " said here the rest of the story:yes: http://www.seateddimevarieties.com/date_mintmark/1840o_104apage.htm
