Week 15

Twenty-Cent Piece + Spiked Head

Monday's coin carries both branches of the Split Die diagram on one piece — a split die on the obverse and a retained cud on the reverse — and it is a half dime, so it calls back to both of Week 13's posts at once. Thursday is a compound error on a 1798 large cent: an overdate you have to hunt for, paired with an off-center strike you cannot miss. Saturday is a first-year 1859 Indian Head with a pre-cud on the one-year Laurel Wreath reverse.
