Jacob Eriq's badge while in the collection of NYPD officer and museum curator Al Young was thought to be from Philadelphia.  His friend and noted police collector Pat Lynch researched Jacob Eriq in the city directories of Philadelphia.  His name was not found.  Ward J. Childs, Philadelphia City Archivist, researched the police roll books for the years 1854 to 1869 and found no entry for Jacob Eriq.  He also checked the city directories for the years from 1854 to 1865 and did not find him.  However from 1840 to 1853 there were some twenty-eight separate jurisdictions in the county.  The following is noted in the Genealogy of Philadelphia County Subdivisions:   "An increasing number of reorganizations in both the City and County were made in the years 1840-1850, which mark an especially accelerated growth in the population of the entire County. The County area outside the City had surpassed it in total population between 1810 and 1820, and by 1853 consisted of twenty-eight separate jurisdictions, eight of which were further sub-divided into wards. There had been, by then, many years of increasing agitation for the consolidation of these units into one City. Again, the need for police protection was one of the chief reasons"  The jurisdictions included:  Southwark, Northern, Liberties, Kensington, Spring Garden, Moyamensing, Penn, Richmond, West Philadelphia, Belmont, Frankford, Germantown, Manayunk, Whitehall, Bridesburg Aramingo, Passyunk, Blockley, Kingsessing, Roxborough, Germantown, Bristol, Oxford, Lower Dublin, Moreland, Northern Liberties, Byberry, and Delaware.

Police Distinction--The day policemen of the city, we learn, are hereafter to wear a badge, designating them as the City Police. The badge is of an oblong shape, bearing the city coat of arms, and the words "City Police," and is designed to be worn on the breast of the coat.
These officers constitute, in the largest degree, the preventive police of the city, and it is questionable if, with this mark of designation, they will be as efficient as heretofore. Although they are more entitled, perhaps, to the character of preventive police, they are, nevertheless, a police detective, also, and perhaps in this character the wearing of such a badge will defeat almost entirely all their efforts to detect the rogues that prowl about our depots, and other public places.

Police Badges.--Police Marshal Kevser mustered his men, yesterday afternoon, at the Central Station House, Adelphi street, and delivered to each man the badge which is to distinguish him when on duty.  It is in the shape of a star, with the arms of the State in the centre, as an ornament.
