This is a so-called Ilahabad forgery of Saurashtra/Sorath 1868 4Ana of a Kori
Saurashtra Post black on white horizontally/vertically laid paper imperf. typeset stamp (SG 15) with the denomination in Devnagari numeral.
Edward F Deschl, editor of the voluminous "The Comprehensive India State Postal Stationery Listing" (1994) first reported these forgeries in 2000 but he rather considerately preferred to describe these fakes as facsimiles/reproductions.
The original typeset stamps with Devnagari numeral
#2794; (4) were issued in June 1868 as part of the Second Issue, in sheets of 20 (4×5), printed by Junagarh Saurashtra Nitiprakash Chhapkhanu, Junagarh which was established in 1867 primarily to print state postage stamps.
These stamps were printed in 2 settings viz., SG/W&M setting IB/Malaviya setting II (horizontally laid) and SG/W&M setting ID/Malaviya setting III (vertically laid).
The Devnagari inscriptions read
#2360;#2380;#2352;#2366;#2359;#2381;#2335;#2381;#2352; #2346;#2379;#2360;#2381;#2335; i.e. Saurashtra Post and the denomination
#2325;#2379;. #2794; #2310;#2344;#2366; (Ko. 4 Ana) i.e. 4Ana of a Kori.
The stamps were continued to be used mostly on parcels (which is why very few 4A is found on cover) till its demonetization with effect from January 16,1878 when the Third Issue was introduced.
All modern Ilahabad fakes of Saurahtra SG 14 show the stamp from pos. R3/2(10) as is also here.
These fakes are invariably found printed on thick white wove paper, which were mass produced in Ilahabad in mid-1990s.
