Plate 3 has an earliest known use date of January 15, 1852, so it was likely manufactured shortly before that date. It was used continuously until some time after February 24, 1857, because some perforated stamps were produced from this plate. All stamps from Plate 3 have inner lines. This plate is notable due to the "three right vertical rows" of thirty stamps, of which nineteen stamps show extra or missing frame lines. Dr. Chase provided extensive plating information for these thirty stamps. Approximately 77,877,600 stamps (389,388 impressions) were printed from Plate 3. Refer to Dr. Chase's book The 3¢ Stamp of the United States 1851-1857 Issue for the full story of Plate 3.
