Documentation on this is surprisingly sparse (and mixed). Why did the mint change transition from 8 to 7TF in the midst of 1878 mintage? This must've been a costly and messy venture, so what gives? I assume as a result of the chaos, all these die varieties arise: 1878 8TF 1878 7/8 TF weak 1878 7/8 TF strong 1878 7TF rev 1878 1878 7TF rev 1879 Can someone explain this mess?!?
Somebody at the mint decided the bird had 7TF and made them change the master die. Both are wrong. They actually have 12.
