There are 568 listing in the Hardy Index System for the 1957D Lincoln Cent. The catalogue was published in 1972 call the “BIE Handbook” Edited by Howard O Hardy. The totals above are for all 1957D Lincoln die breaks "II-F-1 through II-F-8" The 1969 edition of “THE CLASSIFICATION AND VALUE OF ERRORS ON THE LINCOLN CENT” by Jean Cohen has 144 of which there are 60 listing for the II-F-4 "BIE" that have the die chip in the lower "B" in Liberty. Cuds-on-Coins has 93 II-F-4s which we call LDB4. JC
