NGC got it right. Look at the luster between the mint state coin and the circulated coin below it. There's no comparison between the two coins; NGC got it right. The steps are a little soft, however, but a full strike on the steps is not necessary for this grade. All of the others details show. Plus, you also need to take into account the year and mint; in this year at the SF mint, nickels were not well struck, so this example is at least average, and could be above average for the year/mint. This is confirmed by the PCGS price guides. A 1954-S in MS67 with FULL STEPS lists for $50,000. Your example could well go for over $200.
I can't agree with that. Your coin has some significant marks on the collar and some stuff going on in the cheek as well. The NGC coin appears pretty much mark-free to me. On the other hand, your coin appears to have a FAR superior strike. As for comparing the toning . . . maybe I am just missing it, but maybe someone can point me to something where it says that PCGS and NGC are supposed to evaluate how "pleasing" the color of a toned coin is supposed to be.
Actually eye appeal is evaluated and factored into the grade at all of the major tpgs so super nice toning can and will bump the grade of the coin up in a lot of cases.
