1878 7TF Reverse of 1878 Proof

The 1878 Morgan Dollar 7 Tailfeathers Reverse of 1878 Proof represents the second 1878 reverse hub configuration in proof format, struck at the Philadelphia Mint during the inaugural Bland-Allison Act production year after George T. Morgan revised the original 8 Tailfeathers reverse at the Mint's request. The Mint did not separately record per-subtype proof mintages across the three 1878 reverse hub revisions, so the 7TF Reverse of 1878 proof figure is not independently documented in the Mint Director's annual report. Survival estimates place the 7TF Reverse of 1878 Proof population well below 100 certified examples across modern grading service records. The flat eagle breast and parallel arrow feathers distinguish the Reverse of 1878 from the later Reverse of 1879 hub.

Authentication of an 1878 7TF Reverse of 1878 Proof requires careful examination of the eagle breast configuration, arrow feather orientation, and surface character under five to ten power magnification. The Reverse of 1878 hub shows a flat eagle breast and parallel arrow feathers, while the later Reverse of 1879 hub introduced a rounded eagle breast and slanted arrow feathers. PCGS, the Professional Coin Grading Service, and NGC apply rigorous standards for 1878 7TF Reverse of 1878 Proof authentication, and pedigree documentation routinely accompanies confirmed examples. Cameo and Deep Cameo designations are scarce within the small surviving 1878 7TF Reverse of 1878 Proof population, with most examples showing brilliant rather than frosted device contrast typical of early Morgan proof production.

The 1878 7TF Reverse of 1878 Proof is a regular-classification proof entry on this site under the standard catalog convention for Morgan proofs, with the rarity narrative carried in the prose rather than the badge tier. The 1878 7TF Reverse of 1878 Proof is one of three 1878 reverse-subtype proofs and pairs with the 1878 8 Tailfeathers Proof and the 1878 7TF Reverse of 1879 Proof as the matched first-year proof set documenting the inaugural Morgan reverse hub revisions. Auction records for confirmed examples regularly clear five-figure prices in the Proof-64 through Proof-66 Cameo grade range.
