David Akers (1975/88):
It has been estimated that only ten pieces of the 1879 coiled hair stella were struck, but in my opinion, a very small quantity were restruck, probably in 1880 along with the 400 pieces of the 1879 flowing hair stella. One specimen , the piece in the Rio Rancho Estate Sale of 1974, bears pecisely the same kind of very light adjustment marks that are seen on the restrikes of the 1879 flowing hair. Such marks, of course, are not decisive proof by themselves, but considered together with the number of known specimens and the relatively frequent auction appearances compared to the 1880 coiled hair stella (it was offered three more times than the 1880 coiled hair stella in our 238 catalogue survey, but in a check of nearly 200 catalogues back to its first auction appearance in 1882, the 1879 coiled hair has appeared more than half again as often as the 1880 coiled hair), it seems that there was a limited restrike activity. I cannot account for ten different specimens, but since it is unlikely that I know the whereabouts of all existing pieces, I feel certain that there are several additional pieces in collections, museums or estates. For this reason, I would estimate that the total number in existence is probably somewhwere around 13 to 15 pieces.
The Coiled Hair design $4 Stellas are much rarer than the Flowing Hair design as a mere handful of the 1879 and 1880 Coiled Hair Stellas were struck while 425 1879 Flowing Hair Stellas were struck. For the 1879 Coiled Hair, it is not 100% certain how many were made, but general consensus is that the original mintage was around 20 and there are 14 or 15 survivors today.
