I try to avoid "rustic" when I can, but with some coins, you don't have much choice. As I said early the Dahlonega Mint made better coins on average than the Charlotte Mint.
Here is an 1850-D gold dollar. The Dahlonega mint had great superintendent who lost his job to politics that year (change from Democrat James Polk to Whig Zachary Taylor), and the quality suffered. These coins often come with flat strikes, like this one. PCGS graded this one EF-45.

And here is an 1855-C gold dollar. These coins were some of the worst products ever issued by a United States mint. This design was a technical failure because the head of Ms. Liberty was in too high of a relief and the coin would not strike properly. Even the head office at Philadelphia had trouble with this design which lasted for one year (1855) and parts of two other years (1854 and '56).
The Charlette Mint couldn't get this coin right at all. They are all poorly made. This one is graded EF-45. This is "rustic."
