On September 1, Stack's Bowers conducted a Rarities Night session in California as part of this firm's post-ANA World's Fair of Money® auction extravaganza.
The Kagin-11 Humbert $50 appears to be the earliest coin struck by the Assay Office in 1852. These slugs were issued between the New Year and mid-February, when Curtis, Perry & Ward officially took charge of Moffat & Company and removed Augustus Humbert’s name from all United States Assay Office issues. It is the among scarcest varieties of Reeded Edge slug, with only around 75 examples in private hands. Three or four mint state examples are known today, and an original choice AU would be considered a candidate for the condition census.

Greysheet News
Commissioners reviewed reverse designs for the four American Innovation dollars scheduled to be released in 2028 and obverse and reverse designs for the 2027 issues in the Comic Art Coin and Medal Program.
The rare coin market so far in 2026 has been somewhat volatile, with greater price swings happening over a shorter period of time when compared to historical norms.
