N.Y.C.
The Oxford English Dictionary's March 2004 revision contains my 1869 entry as the earliest for the initials "N.Y.C." representing New York City. "N.Y." is far more common.; "N.Y., N.Y." had also been used.
From the Oxford English Dictionary:
1869 E. H. GILLETT (title) Sermon on the character and labors of the late Rev. Jeremiah S. Lord, D.D. Pastor of the Reformed Church, Harlem, New York City Preached in the Harlem Presbyterian Church, *N.Y.C.
